I raised request for Airtel fiber connection on 5 April 2021, I also made the payment on the same day through generated link. After that I did not received any call or messages from Airtel. After 3 days I contacted Airtel through email and phone. I was given different time by different customer care executives. but when the given time ends, a new date was given to me.
so, I cancelled my order on 20 April 2021 due to delay in installation. He gives SR NO.[protected] to me and asked to wait for 7-10 days. On 22 April, I received message that your complaint[protected] has been resolved.
But when I spoke to the customer care executive on 23 April, I found that my request for cancellation of order has not been accepted yet. Again, I request him to cancel my order and refund my money. He asked to wait for 7-10 days. On 25/04/21, I mailed to nodal team for confirmation. He replied me on 26/04/21. According to the mail, now my order has been cancelled on 26/04/21. This means that the request raised on 23/04/21 was also not accepted. On 27/04/21 again he mailed me and asked for cancel cheque and bank details for the refunding money. I share all bank details. On 28/04/21 he again mailed me and asked to wait for 7 days.

After that I did not received any messages regarding cancellation, so on 02/05/21, I again mailed to Airtel. On 3/05/21 he replied and again asked to wait for 7 days from that day. On 6th may, I contacted to Airtel Appellate Authority. He called me on morning and asked to wait for 48 hours. But in his mail he asked me to wait for 5-10 days.
From more than 17 days, I am taking follow up for the refund, but no solutions is given by Airtel team. Only time is being sought again and again. When You were not able to give connection to me why you are holding my 2829 rupees. I have even applied 17 days back for refund through call you also provide Service Request No[protected]. but why Airtel literally not doing anything.
I don't know what is happening, neither the connection is provided and nor the refund is given back. Is this the Airtel services to the customer?
Many times the 3 days and 7 days are gone and I am fed up of 3 days promise from Airtel. Kindly, refund my money to me immediately. You hold my money from more 30 days. Why?
