Stressed out on account closure

I have paid my balance of R205 but instead I gave R220 thinking it will settle the account. I emailed them, back and forth and on the 16th I received another email I must pay R39.58 thinking my account is closed then I send another email The reply was I must first pay the R39. 58.so i did and immediately send the proof. A lady named gusna kader reply was I must wait till it reflects and only mb by the 20th.so that means if not then by that time debit me again for service render... What service? More like stress yes. I am tired of these back and forth email begging them to close my account. Is this how woolies rip people off? And all they keep sending is "thank you for your email your query matters we will get back to you in 24hours" ,but never does. It is so stress full. I cannot focus at work because my mind is on this unsolved issue. The saddest part is I cannot walk around at work, but they can contact me after hours or jyst close the damn account, I have srnd them my ID and account details but stil nothing this is my 3rd bad experience from woolies. They are *********** and I regret the day I agreed to a credit card.
