Poor aftersale service and incompetence

I don't normally do reviews but i am writing this note with disappointment . I bought a refrigerator at Beares in Boksburg CBD. The consultant that I have been in contact with has sinnce left.. After they delivered the fridge and I opened it, I noticed that there were dents in the back of the fridge and took photos. I sent it to the consultant who assisted me with the purchase and was advised that it will be taken up with the store manager (Gabriel). I have not had any feedback with regards to this and another point is that no one at the store knows how to set up a debit order properly. They take your bank card and initiate the debit order only for it to go off on different days than what my salary date is and then keep calling me and asking when the payment will be made when this is not my mistake, but theirs. In saying so, my account has fallen into arrears as a result of their incompetence and want to know what Beares/ Lewis Stores will be doing in this regard?
