Poor Service

Good Day

I keep on receiving an sms from Capitec Bank , stating that I am owing them R2.60. I have phoned in numerous times and was told they are going to write it of ,as they debited my account. This morning a debit order of R71.72 went off my account from Capitec. Please explain this. R2.6 vs R71.72????And by the way the R2.60 are reflecting negative on my credit reports , as it show i missed a payment. Please fix this. My account was each and every month up to date
