Perfect Interiors with curtains and Wallpapers - Faulty Product

Hello there. I am reaching out to seek your expertise and legal assistance regarding a distressing experience I had with a shop owner, Mr. Sudeer Bhandary, at Perfect Interiors with Curtains and Wallpapers.
On September **th, ****, I placed an order for a customised wallpaper at his shop, located at Shop no LG*, Marian Paradise Streak, Bejai Church Rd, Mangaluru, Karnataka ******, India. My interaction was primarily with Mr. Sudeer Bhandary himself, who took the order and assured me of the finest quality product.
During the order process, I provided a picture of the desired wallpaper via email, as requested, and later visited the shop in person to finalize the details. I trusted Mr. Bhandary's recommendation to upgrade the wallpaper to High-Definition print, believing it would enhance the overall quality. Accordingly, I made a cash payment of Rs.**,***, looking forward to receiving a beautiful addition to my home.
Unfortunately, things took a bitter turn when I opened the package containing the wallpaper on October **th, ****. To my dismay, the customised wallpaper was of subpar quality, featuring an undesirable "oil drops" like print that diluted the entire picture. I was deeply disappointed and felt cheated by the outcome, considering the hefty amount I had paid.
In my effort to address the issue, I contacted Mr. Sudeer Bhandary via WhatsApp, providing pictures and videos of the faulty wallpaper as evidence. Initially, he acknowledged the problem and promised to rectify the situation by providing a new set of wallpapers from the supplier.
However, my struggles did not end there. In March ****, during my visit to India, I made several attempts to meet Mr. Bhandary in person to resolve the matter. Following his request, I engaged a photographer to provide new pictures for the replacement set, incurring additional expenses of Rs *,***, along with the cost of a USB drive.
Despite my efforts, the scheduled meeting on March *th was cancelled, as Mr. Bhandary claimed to be unwell. On a subsequent visit, I was informed by the staff at his other business in the same building that he was unavailable. This evasiveness and lack of accountability further compounded my feelings of disappointment and frustration.
Having exhausted all possible means of direct communication, I entrusted my uncle to deliver the USB drive with the new pictures to Mr. Bhandary's business. Regrettably, since then, he has chosen to ignore my messages, calls, and emails, leaving me without any resolution or refund.
To summarize, my financial losses due to this unfortunate experience include:
*. Rs **,*** for the inferior wallpaper.
*. Rs **,*** for bulk luggage charges at BLR airport.
*. Rs *,*** for additional luggage charges at Mangalore Airport.
*. Rs *,*** for the photographer's services and expenses.
I am now at a point where I no longer have any use for the wallpaper, and I am seeking your legal guidance on whether I have a valid case against Mr. Sudeer Bhandary. It is my earnest desire to recoup the funds I invested and ensure that he learns a lesson in customer service to prevent others from facing similar hardships.
I have documented our entire communication, including photographs of the faulty goods, on WhatsApp, which I am willing to provide as evidence to support my case. As per my availability, I can be reached through email or WhatsApp during your mornings (India time) on Saturday or Sunday, considering the time difference of six hours. My Whatsapp number to call on the above days is +***********.
I understand that this matter may seem trivial, given that it involves wallpaper, but the emotional toll and financial burden it has caused me a lot of anxiety and stress. I trust in your legal expertise and compassionate understanding of the situation.
Thank you for taking the time to read my account, and I look forward to your valuable guidance on the best course of action.
Yours sincerely,
Wilson
