Bad service

Good day I have a Loan a/c at Woolworths which I paid up in January 2025 I was not aware of a settlement amount that I had to pay I went into Woolworths at trade the lady that helped me was very nice nice she put on the with the personal loans who gave me a settlement amount which I paid after a few days I phoned to find out if the a/c is close it was not closed cause had a r1.00 balance which I ask them to write it off up till now it it not written off I checked on the Woolworths app just to find out that I owe Woolworths again I spoke to a lady by the name of fathina khan who promised me it will be close It is frustrating and costly Iam a pensioner I have to buy airtime every time and still get cut off and when I speak to a consultant they cannot phone me back Iam very upset
