Dear Sir /madam

I have visited Airtel office on 16 july 2018 for conversion of my postpaid connection to prepaid connection, initially they started with technical issue but ultimately they had to take the request and confirmed the TAT of three days, it's been one week now still it did not happened I reached CC every time that said 48 hours and 78 hours unexpected from Airtel
Please help me.
