Laksshmi Decors Home Designs - Got cheated by Decors Shop for Mosquito Mesh

In our Native village, there are lot of insects and mosquitos around the house and as it is summer we planned to put Mosquito Mesh to the windows and the main door. As part of that I have reached on of the Decors shop in Tirupathi recommended by my brother which is Laksshmi Decors. We contacted them and a person named Sathish from that shop has come to our house and taken all the measurements of the windows and main door. After bargaining the amount was finalised to ***** for which he asked an advance of **** which i have transferred to him through PhonePe on Feb **, ****. The screenshot proof for the same is attached. he promised that the service will be done with in a week i.e., by Feb **, ****. After that Sathish did not answer my calls from the next day and we started calling the owner of the shop Ramu who use to tell that Sathish is on leave on emergency for few days so he cant answer the calls. he said the service will be done by time. From that day, he kept on postponing the service for many weeks. Till date the service is not finished. everytime we call he says, we will come and finish day after tomorrow. he keeps on saying that everytime. and he rejects to give refund as well. He does not finish his job and wont even refund the money. after few days he started not answering the calls. Finally he said, you can come and take the sliding door mesh for the **** you paid, and get it fitted from any other shop. which is not at all acceptable because he made us waited more than * months and our parents suffered a lot with mosquitoss, insects and heat in summer.
