MBD credit solutions *********** clients

The company is debiting a certain amount from my bank account of which we reached an agreement that it will be the last day of each month. To my surprise, they debit not on the agreed date and the bank penalizes me every time an unsuccessful debit order occurs. I’ve called the call center multiple times to resolve this matter only to be told that the issue is resolved but yet the same issue has occur three times. When I complain about my refund, they suddenly have no interest to assist me. I’ve sent multiple emails to their customer care without any assistance. I’m basically being **********. Mind you, their calls are recorded.
