Acc was closed, no notification - shop cannot help

I have been a Mr Price home ciustomer for more than 8 - 10 years. I paid up my account around Septemebr 2015 and on Saturday, I decided to shop. When I got to the till, I was told there are no details against my name and that I should call the head office. I tried the whole morning in Sunday to call, there are so many numbers on their website until I got discouraged and I called the Phalaborwa branch to call on my behalf and try to sort this out for me. A guy at the shop took down my details and promised to call back and a day later, still no phone call. I again called the shop and I got this Rude woman, who does not understand why I need the shop to sort out...I wasted my time by co-ordinating d?cor, which I couldn`t take home. The branch never tried to sort this out, to call or email or anything... What is this? This is the thanks I get for paying my account up-to date??? Do you know how embarrassing it is to shop and queue and not take anything home??? Why was this account closed in this first place??? i wasted my airtime and time, trying to resolve this mess. In the time I have been a client, I know I spent at least R80 000.00 or more on Mr Price... I am very disappointed!!
