Shocking treatment by Foschini

This us the shocking treatment my sister received from Foschini:

I have been an account holder with Foschin for over 40 years, and have now closed my account.I was a few days late with my payment, which was about R60, as I was out of the country, only to find that Foschini added R150 onto my account. Shocking treatment of clients, despite me gaving this account for over 40 years. - I was told to read the fine print !!!!! Never will I set foot in this dishonest business again !!!!
