Pathetic after sales Tech service.

Good day,

This is my 3rd year with supersonic, never had any issues up until recently. I have a 10mb up and down line. within the last 2-3 weeks I have been experiencing intermittent download and upload speeds. sometime I get 1 mbps and other times 4 then 8 then 10 up and down. I have logged a ticket with them ysterday nearly 24 hours later and have been on the line with Smart tech support for 30 minutes, This is my 3rd phone call to them . First of all they say they cant transfer me to supervisor/managers. Then they said I will get a call from the faults dept after 4 - 8 hours. Then they said they will try and get hold of the faults dept. been on hold for 20 minutes holding for them. Pathetic services, from a company that was taken over from MTN a couple of months ago...... Supersonic needs to get there act together. And like usual nobody from Supersonic/Mtn will take responsibility for this. Or even bother replying
