Worst treatment offered by store manager Mr Russel Nkoane

I went to jet mart store at The Bridge to buy a fitted **** for my bed, by mistake i picked up a bad wrap, i only noticed when i opened the plastic when i am about to put it on the bed, I put it back the plastic and returned it to the store for a exchange, the store manager Mr “Russel Nkoane” was so rude and had no intention to assist me as a customer, i asked if i can exchange, he said no what I brought back is already damaged, i then asked if he is trying to tell me that they sold me a damaged product because i never used the item, I returned it as soon as i realised it was not the right thing i wanted, he even lacked the product knowledge, he told me that “I am taking him back to school” because i asked questions he had no answers to, i then asked for a copy of the return policy, he said he does not have it at the store he needs to request it from head office, i mean which store doesn’t have that? I asked if it can be emailed to me after requesting but Mr “Russel Nkoane” the store manager said i should just drive back to the store after i told him i will be at work. Does all Edcon stores do like this? Or is it only Jet? Or specifically the one under Mr Russel Nkoane? I honestly feel Jet should teach the management how to speak to customers instead of management telling customers that it was their negligence, i was told straight to my face that “we are running a business here, we are not here to exchange goods because they don’t fit your needs” Y do they even accept returns if it is like that? Jet store at The Bridge is not a store one can recommend to the next person.
