BAD BAD SERVICE SINCE I HAVE BEEN A CLIENT, 5 Years, still terrible, every interaction

So we are at it again, Supersonic takes you money but does not want to service their clients. Took me 25 days to upgrade a connection due to very poor client services call centre not anwering calls, whatsapp numbers that takes a whole day to answer, and when they do and you dont respond quick enough that close that chat. Now it been 6 working days to try to get my connection that is supposed to be upgraded fixed, to only notice that they still have us on an old adress that we moved from almost 5 years ago. And guess how long it took to sort that issue out ?? 3 months and I am am being honest, and suprise the issue is not resolved. I will be taking this complaint to ICASA and I will get the connection cancelled so that I can choose another ISP over VUMA. If you care contact me on ***
