Supersonic, can not deliver on sold services or pre or post sales services

Before being part of MTN things were OK.

No Pre-sales or after sales service. Users wait weeks for implementations in a large estate. The Large estate with lock-in to Supersonic has terrible connectivity during peek business hours. Continuos network time outs, high jitter volumes, difficulty maintaining voice communication services like Teams and Zoom.Browser pages timeout, emails timeout. Many many hours spent with servicedesk over months to attempt to resolve.
