Airtel — delay in shifting an existing connection

Address:

560103

Shifting request initiated on 19-dec-2017. Even though it is told 3 days is the maximum time, not yet done. After 10 days, they are claiming, no able to contact me. Then next, claiming the new address is not traceable. Now claiming some port is not available.. Etc... The worst part is no clear intimation of what is happening. I will have to cancel this connection ad look for some other provider
