SIM cards suspended

So I have been having endless problems with this company, so after fighting for almost a year to get a refund for my husband to pay my account that was paid incorrectly, the refund has been paid, I have spoken to a nice guy by the name of Tafadzwa who helped me, so now that we have the refund we want to do a payment and guess what I can't get hold of this guy I refuse to speak to anyone else but him so who ever gets this message ask him to call me coz I'll drop the call if it's not him and I know his voice so don't dare try and fool me. Ok so me and my husband's both our SIM cards are now suspended and my son was using this number for college where they send links for his work and studies and his not getting anything anymore so if I don't get a call from Tafadzwa today they have left me with no choice but to reply to the ombudsman email and say issue not resolved.
