You Broadband India Ltd — refund not given

Address:

560070

I asked for a broadband connection (3rd aug 2018) for my house for which i gave them inr 3900/-. After taking the money they called me and told me that they will not be able to provide the service to my area and refund will take 45 days time. I have made several calls to them and sent multiple mails but they keep telling that their technician will call and let me know when i will get my money back. Till date i have not received any calls from them neither they have returned the money.
All i have is a stupid ref no[protected] which they say they don't know
My account no with them is 1783998 which i feel is a dummy one
