*****ulent activity on my Exact clothing account in Idutywa

I have an account with exact and took items amounting around R500 , My monthly instalment was around R50 and I decided to pay R100 every month so that I can payoff the account before time . I was surprised to know that I owe an amount of +-R2000 and when I enquired about these charges , I was advised to come to the shop for them to be cancelled. I never agreed with anyone to activate services in my account , simple because I am a pensioner and cannot afford to pay for things that were not given or rendered to me. This is a pure ***** and this matter will be escalated to the consumer ombudsman as I never agreed to activate any other services on my acvount. I had contacted the shop at Idutywa branch and the person who assisted me could not even tell me what the charges are for and it is very disappointing to hear that .
