Airtel — airtel postpaid dongle not working

Address:

Pune, Maharashtra, 411014

My 4g postaid airtel dongle number is [protected]. My airtel 4g dongle wifi not working for last 2 weeks. Raised at least 7 complaints but no use. Their useless customercare is saying that they are not able to access my profile data. I have escalated this issue to their supervisor. They told me that they created a service request which will be closed by 10hrs but after 24 hrs also nobody contacted me and issue is still not resolved.
