Stop subscription charges!

So my 60 year old mother is trying to pay off her account at Foschini. Every time she speaks to the call centre people to cancel the unnecessary subscription so her bill can be less. One of the consultants told her she needs to go to the store to do this. Still they are charging her this has now been going on for over a year. One of the collection against even went as far as telling her it's not her job.

Can you please just stop these charges so my mother can be done with you and your bad services
