NO COMMUNICATION

Hi there - i am trying to sign up with Supersonic (MTN subsidiary) for fibre to my home. they have a horrible communication method of only calls and whatsapp. the whatsapp is not answered when I question as to the status of my application!! its been 2 days now!!! what is going on? i havent even started using this company and I am already skeptical of the service? No response!!! I cannot cancel as well as they have this CLAUSE of a cancellation fee! how can that be when no services have started?? any lawyers on this platform to assist me! i want to retract my application. I have made no payment, they have not contacted me for installation etc!
