Click Galleria Disgusting customer service

A family friend had gone into the store to do an electric return at the clicks Galleria Mall.It was the most disgusting customer service i have ever seen The item was a clicks brand and he had previously returned the item however the product was still a problem. After going through the process of testing or having a glance at the item,the member of management on duty had asked the customer to wait for an hour in the store.After an hour he was then advised to take the return to another store. At this stage i was asked to assist him as he now had to drive to the next center in an attempt to exchange the item. upon arrive i questioned his position at which he rudely emphasized he was the manager on duty.I am well aware of clicks protocols and management system so i again questioned his position. when i challenged his actions in solving the problem at had he then went on to saying he would ask his manager,who at this stage was still unaware of what was going on. after threatening to report him and his behavior he hesitantly returned the product and had the nerve to state that he didn't want to argue and that he was doing us a favor. the item was changed for the same clicks brand product that just had a different sku i find it disgusting that clicks instates people like this into management roles that abuse their position.They do not uphold clicks values or adhere to return policy's. their response and willingness to assist is 0% During this entire ordeal not once did he apologies for his behavior nor show remorse for his actions I feel he should be removed from management until he knows how to handle customer interactions correctly
