Poor service

My mother is a foschini account holder however she lost her job in 2016. We informed the store and they said there is nothing they can do nonetheless she tried paying the account but later realised that there are "financial products" that make the balance not to reduce...we went to Jabulani Mall to cancel those more than 4 time all they did was give us a form to fill in, to date they have not cancelled their financial services we even tried an alternative by going to total sports to cancel but still nothing is happening! Stop taking advantage of vulnerable and older people
