I dont understand the arrears amount?

Your call centre is not being answered. While I appreciate your services, please fix your system so that it works. There was a debit order for R679 that went out of my account on the 28th asper agreement however, I see now on my online portfolio that there is another R195 or so that is scheduled to go off in May and that is the amount in arrears? How is that possible?<br> <br> Please can somebody call me to explain because you guys only answer when it is convenient for you.
