Supersonic debits off my account double the amount every month

Terrible Customer Service They debit double the amount of my account for 3 months. Ive been emailing them and there is no contact details or anyone to call to discuss. I tried to escalate with no result. I'm not even a Supersonic customer, i was with MTN and they merged so i automatically became a client. No comms or feedback. Shocking service - i'm going to move to another service provider with more visibility and communication. You lost a loyal customer Supersonic.....
