Over deduction of instalment

It's now almost a month since the incorrect debit order by Makro. I had to borrow money already to survive for the month and there feedback thus far has been absolutely minimal. I received an e-mail once to advise that the matter will be escalated, then another to advise that was a technical error on my account, but no further feedback as to when I will be receiving an amended account and what is going on with the refund of the over deduction. I have never seen such bad service from a company and then they still try to get you to apply for cash loans by them. It's like they are just ignoring reviews and e-mails being sent to them, but still expect people to buy from them. I am absolutely disappointed and will dissuade anybody to open an account with them or support them until such time as my account is sorted out.
