Consumer Redressal

I applied to change from Airtel postpaid to Airtel prepaid. I submitted the documents and got the prepaid SIM. I was told that postpaid SIM would get deactivated in 4 days and then prepaid would get activated. Few days later, the postpaid SIM got deactivated but the prepaid SIM was not getting activated. I contacted customer care who kept transferring the call between prepaid and postpaid departments. I spoke to 7 people. the 6th person I spoke to told that they did not receive documents and hence they cannot activate the prepaid SIM. How did they deactivate the postpaid SIM without receiving the documents? I asked that question and the person was unable to answer. He then told me he will transfer the call to the supervisor. I explained the problem for the 7th time. The supervisor gave the same answer. They did not receive documents and hence cannot activate prepaid. He will not answer to the question "How can you deactivate postpaid without getting documents?" Affected num :8123842560
