Unsatisfactory Customer Relations

On Tuesday I was informed by Best Home and Electric in Alberton, of my account that has not been paid to date - initially i had setup a deduction for this account to go off from my account.

It seems like their accounts person(s) did not follow-through with what I had signed, for the debit transaction.

No one can account for what happened, instead I was told that Its my responsibility.

Their carelessness/negligence has messed up my credit profile. I have also escalated this matter to the head office, and on their system it shows that my debit was cancelled.

Who can I speak to; regarding this issue.
