Airtel — airtel 499 offer for mnp at 349 - a mess

Address:

Chennai, Tamil Nadu, 600094

Just moved today from tata docomo to airtel (499 offered at 349). Have been following up with 121. Their network is so bad (4g, 3g and any other with mobile data and without) that their customer care is not able to hear me. The airtel associate who provided the sim and did the registration is not available - his phones switched off. Had asked for a 50 rupees isd rate cutter pack. With difficulty if am able to reach 121 they claim am on unrelated pack 399. Now am not sure where am landed. (Currently am located at ambattur when have changed the sim today)

On the contrary a jio connection seems to be entirely reliable. It is just that they do not have the isd pack as yet.
