Supersonic bad service

Mtn supersonic has the worst customer support and technical support. They advise customers to log queries or receive support via the WhatsApp chat line which is most frustrating. It is impossibly to get and answer and query resolution. When you call the centre you wait a long time for a response. I logged a query with supersonic technical ref CAS-19223-V1V0-V1V0H0. The technician advised to switch off my router and white box for half an hour as there was a major cable fault in the gauteng area. I did that and my internet is still kot working. He also mentioned that he will call me back in half an hour and never did. Customers have to constantly beg for service inspire of paying for the service. This is pathetic from myn supersonic.
