Supersonic by MTN is the worst ISP ever STAY AWAY

After 5 days of waiting, still no Internet service provided by Supersonic. Supersonic can only be qualified as super useless. 1) Vumatel fibre provider has proven to me in 5 minutes with a great tech agent that Supersonic has not activated the internet service on my fibre line that is 100% up and running. 2) Supersonic is clueless and claiming that the problem comes from my router, this is insane 3) I have even provided Supersonic with payments in ADVANCE and still they are unable to solve anything and reactivate the service 4) The call centre of Supersonic provides the WORST possible service or no service actually with agents NEVER calling back and NEVER sorting issues
