Airtel — signal coverage

Address:

641606

I am Manikandan for Tirupur (Vijayapuram). (641606). I called 198 many times and complain about my signal coverage. But Airtel customer care simply says "We will clear the issue". But till now I have no clear signal strength. I am so 3 G user. But our area 4 G users suffered too. First time I called for Customer care. They simply asked for area and replied me for the resolution in future. They also done a customer survey for customer care staff'ss work. They eagerly do this heavily. But There's nothing done for my complaint.
