Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

Transaction for charging mobile number initiated from vodafone app and payment done from mobiwik. But transaction failed at mobieik end and refund not initiated in account while 7 days already completed. I already raised complain to mobiel but no update and refund initiated from their end. And they never respond on any complain. I am still waiting for their response but no response from their end.
