Putrid and pathetic

I have had an account for about ten years. About 5 years ago I paid the account in full and asked if it will stay open to which I was informed is possible. Since then I've been using the account as and when which could be about once a year. Today I went to get my child's school clothes, only to get to the register and find out the account is closed. They called their head office, the person on the phone, Thembeka, was very condescending and belittling towards me and had such a bad attitude. The staff and the manager was not of much help. When I displayed my utter disgrace and asked for the area manager's details, the other cashier laughs and jokes with his customer about me. It took an hour out of my day not only to be humiliated in the store, by the staff, but also to have a financial setback as I paid cash. How can a company close your account without notifying you? Then I was told I must bring bank statements and proof of address to open a new account??? What ridiculous world is this? Putrid and disgusting does not even begin to explain the service! No further help from the manager, no offer to get the matter sorted. Violating the POPIA and Consumer Protection Act. Being humiliated infront of my child and all other customer there after being a loyal customer of the brand for many years. I didn't just spend a R50 there, I spent close to R1000. Yes I wanted to just leave everything and go to Woolworths rather (where I also have a zero balance account for years which is still active) but I did not want to be further humiliated looking like someone who has no money and just wants to make a scene. I am a single mother, making good financial decisions and trying to teach my daughter well as well but she must be exposed to disgusting behavior like this! Unacceptable!
