Super sonic Fibre South Africa

Internet been off for 5 days. Did report on day one. Made about 7 follow up phone calls. All they say is they will escalate the problem. Now starting blame shifting. Saying it is MTN and that they must make contact with me. My contract is with supersonic and I got nothing to do with MTN. if they use MTN then they must sort it out with MTN. Not me.
