Credit card complaints

On the 15th i went in store, asked for my settlement amount and also informed the lady helping me i want to pay so i could close my account, she called and gave me my amount, i went back the 16th and paid the amount that was given to me nd were informed to come back the next day coz it takes 24 hours to reflect and i could only close it then, the 17th i went back to close just to b informed i cant close coz i have a balance on R161 i also receieved a email on the 17th with my balance, this is after i paid my "settlement". I had a argument with the lady helping me til closing time, so i couldnt pay it then, i went back yesterday just to b informed the amount of 161 now is over 200.Ive paid settlement amounts before nd never in my life did the ask me more than what my balance showed on my statement, infact its always way less coz the interest falls alway, i was very ****ed coz Myson(the person helping me, wants to explain to me the same thing over and over). I told him il pay the amount right now, and then i want my account closed, he then says i can only close it in 24 hrs, but he wil monitor my account. I told hm i refuse to come back, ive been doing it for a week now, wil he cover my petrol expenses coz i live far from mall. I told hm to close my account as soon as he see the payment reflects, and i expect a call from hm to say its closed, coz thats the least he could do, i asked hm his name and surname (he refused to give hs surname) hs name is myson, he told me he cant guarantee to call me back, i said he is responsible for my account after this, and if they want to offer me increases they call me everyday, so whats the problem of making one call.im disgusted and utterly dissapointed with the service, i feel they ****** me
