Vodafone — Postpaid to prepaid migration issue

Address:

Hyderabad, Andhra Pradesh

I have visited Vodafone store and submitted by photo and address proof to migrate my corporate postpaid to prepaid. As suggested cleared by due amount in cash, till till the vodafone has not migrated the number to prepaid. Customer care executives are not able to provide any update, no amount pending on my account.Escalated the case to Nodal and Appellate authority but no response received from them. Unnecessary billing happening from not migrating the number. Please let me know if there is any way to do it. My mail ID [protected]@gmail.com and number [protected].
