Quantico Global India Private Limited - HDMI Projector received recently and malfunctioning but no support response from the company despit

Kindly note that I had recently ordered a Sketra GB** HDMI Projector from M/s Quantico Global Trading Pvt Ltd, address Shop No. **, Balachaur SBS Nagar, Nawan Shehar ******, Punjab.

The unit was delivered on *th August morning to my premises in Koregaon Park, Pune ******, and delivered in its original carton with no protective bubble wrap or covering.

On powering up as per the instructions provided, only the projection lamp came on, but with none of the other control buttons functioning, either on the unit or on its remote control.

I called the Quantico/Sketra customer support no: ***********, as provided, and was directed to a service advisor, who just cut the call with no further response.
I also called their director, Mr. Shubham Chhabra, as per his available number: **********, but he too declined to attend the call, following which I sent a sms and a whatsapp message to him informing of the problems faced and the need for support, but he did not care to respond,
and in turn blocked my mobile no from both the Quantico customer care no and his personal number as well.

I also sent an email request for the same to their support email address: info@sketra.com and on their facebook link as well, but with no response whatsoever.

My wife called Mr. Shubham from her mobile no on this Saturday and as it was not my mobile no, he took the call and promised that some one from Quantico would call on Monday, which was yesterday, to help resolve the problem.
However, as I did not receive any call, both I and my wife tried calling on both numbers but he did not attend to any calls and kept cutting calls. He is not responding to any calls henceforth.

I have paid Rs.**,***/- for the projector and if they cannot resolve the problem soon, would want to return the unit and get back a full refund for the amount paid.

Please find attached a copy of the projector order and product details, the delivery invoice, the despatch and delivery tracking details and Quantico address details.
,
I am a ** year old retired senior citizen being put to unreasonable duress by this company and its staff, with no support whatsoever despite quite a few calls, email, messages, appealing for help.
I am indeed very upset with the manner in which this company seems to treat its customers.

I hope you appreciate the quandary and would be highly obliged if you could please help resolve this problem as appropriate and at the earliest.

Thanking you in anticipation.
