Woolworths Account Being Overcharged

I have been a loyal Woolworths customer for years. I have an account with them with a limit of R6000. At the beginning of January 2020, I had an opening balance of R4969 & before 25 January 2020, I spent about an additional R1800.

On 25 January 2020 I made a payment of R3000. On 10 February I got the following 3 charges from Woolworths that I am not actually aware of: (1) Monthly account fee of R25 (2) Interest of 23,75% of R137 (3) Comprehensive Insurance R32 On 24 February I went to Woolworths at the Grove to pay my account but I inquired first & I got tole that my account is at a balance of R6777. This did not make sense as my limit is R6000.

I called customer care (head office) & the consultant (Christian) told me that the account looks incorrect & that the calculation is wrong & that he will escalate the matter & that he will call me back at 16:00. He gave me the following reference number ***.

Christian did not call me back even after I told him my serious concern that I'm afraid that my card could be used **********ly. I am extremely worried & dissapionted in the service I got from Woolworths & I am considering just closing my account with them.

You can check my credit history with them as I have been really good & loyal to them.
