Hi, i am one of the airtel customer. My airtel no: [protected] (My geo location is srk arcade, ft no.105, brindavan colony, bangalore 560029.) i have recharged with rs. 399 plan for 84 days.in which consists o[censored]nlimited talktime validity and a daily quota of 1.4gb 4g data. Right from day 1 i'm not able to use 4g services on my handsets. Even though my handset is 4g compatible. The same i complained to
Airtel customer support team, but its been 40 days still my issue was not taken care of. They simply saying we escalated to network team, as soon as possible they will fix it. But its already went 40 days, still my issue persists.
Airtel customer support team is not considering my issue... They simply seeking time but none is fixing it. Whenever i give a call, they say we are taking inputs and escalating the same to network team. But they are not providing any status regarding my issue. They don't have whether the network team is working on my issue or not.
I have connected multiple times to floor manager... They simply keep on raised tickets on my number. But all of them are in open status. Here is the upic reference no.:ccnor[protected].
Out of 84 days of my plan...40 days i'm out of 4g data services. July 23 my plan will be expire, but still they seeking time to fix it. No one is taking action regarding my issue. I asked them to provide the general manager no, but they haven't provided. So please consider my issue and provide a resolution.
