Cell c and MBD useless

I managed to get someone at Cell C to call me after my Hellopeter review. What a joke the consultant mailed me to say my number is not active so they can’t call me. This is the same number I get calls in daily. I checked and mailed her back to say the number I supp**** is correct and she could call Me ASAP. Again same mail they can’t get through to me. I then called her on numbers she supp**** With no joy. I mailed her again this morning because MBD is still sending messages demanding payment. What a joke Cell C and MBD is. Zero service delivery
