Horrible service

I am disgusted with the accounts department at Jet head office. I was told that my card is blocked because I have reached it's maximum limit. I have last purchased on the card in January 2022, and have been paying the monthly installments in full diligently every month. When I asked the question as to how my balance has not reduced despite my full monthly payments, Roberta the floor manager said that she will investigate and call me back on 21 July 2023. There is still no communication made.
