Zero service

Last Saturday I woke to a pleasant sms informing me that my service had been suspended because I had Gone over my credit limit, despite the fact that I have over R1000 worth of available talk time. I went to the Cavendish branch where the gentleman informed me that an error had occured on mtn's side causing my subscription to be more than my credit limit. He unbarred the line for me but hold me it was going to keep happening every billing cycle and that I needed to get hold of the call centre on Monday morning. I have tried all week with no success. I realise you have issues with the strikes but that doesn't make this acceptable. I am currently pregnant and expecting soon and cannot afford to keep having this happen. You cannot charge me for a service that I am not receiving so I suggest someone contact me to resolve this matter asap.
