Sick and Tired of being bul**** MDB

I have a Direct Axis loan account with an agreement to pay my instalment on the 20th of every month. I have never defaulted since then. I received a sms on the 14th November that MBD will track my account for sufficient funds which ignored because its 6 days before the 20th and of my agreed debit date. Subsequently, on Wednesday, 15th a debit went off my account which was MDB. I immediately called to query the debit and was asked to send an email requesting a refund. I called again the next day which avail to nothing. I still have not received feedback or a call as they promised and still waiting for the refund. I am sick and tired of being bul**** by big corporates who think that they do as the please and gets away with it. I feel embarrassed to be treated by unprofessional agents who sits behind the phone and speak to us anyway they feel like. I guess i can forget about getting my money back as request.
