POOR SERVICE DELIVERY

I have been receiving poor service from Supersonic. I had a issue with my router that had no network, I logged a ticket for them to investigate yesterday and up until now no one has called to provide feedback I had to call them or make use of their whatsapp platform to find out what's going on, everytime I got the same answer from them that the matter has been sent to another department to be looked at and I will be contacted. This is really frustrating the least they could of done was to call and inform me on the process going forward. Supersonic has this don't care attitude and after being with them for 3 years I'm actually considering other service providers.
