ATROCIOUS customer service regarding *****ulent activity on account.

I opened myself a Woolies store card in Oct or Nov I think, all's well I get approved. I wait almost 3months for my store card which I eventually got in like middle Dec. All's well I get some Christmas gifts on account and then the last purchase I made was on 22 Dec. When I try and make a purchase again on like the 10th of Jan, I get told that the last time I purchased, I had overspent by almosr R300, which is IMPOSSIBLE as I haven't by this time even utilised a 3rd of my credit. Turns out on the 4th, 5th & 6th of January someone had spent over R9000 on my account without Woolies even picking it up. Bear in mind I'm STILL supposed to give my ID with every purchase as my account is still very new so I have no idea how they even let that happen. None the less the purchases were disputed and the money was put back onto my account. The problem now is, my interest rate shot up due to the *****ulent purchases and they have not rectified it. after speaking to probably about 12 different people, going into Woolworths and having them phone people, emailing two different people to get this damn R535 taken off of my account NO ONE is willing to help me. Each time I get through to someone they say sure ma'am, the matter has been escelated and will be resolved within the next 24-48hrs. IT'S BEEN ALMOST 2 MONTHS. I get harrased by the finance department everyday asking why I haven't paid, I explain the situation and all they can say is go into the store or phone these people. Today was my last straw when one of the ladies phoned me and told me the excess amount was due to me under paying my account and not paying for Feb. I refuse to pay my account until this matter has been resolved. This is the most atrocious form of customer service I have ever received. I feel let down and as if my privacy to my account isn't cared for at all. It's unbelievably frustrating to not get help from anyone. Although I must say the in store personal at Springs Mall are absolute angels, they have sat with me for hours trying to resolve this but yet, still no conclusion.
