Dismal Supersonic Service

Our fibre connection through Supersonic keeps dropping. Called their useless call center on 2 occasions with no joy. My last request was for them to send out a technician to which they rep**** 30min later on the call, I must do a speed test, with no guidance on how to do it. Their online technicians are useless hence my request for one to come on sight. After 2 weeks, they finally said one will be dispatched within 24-48 hours. No reference to this action, so fingers crossed, it is a wait and see. The company has extremely poor reviews on Google and if there was an alternate service provider in the area, I'll immediately change. Very disappointing and unprofessional customer service especially when I work from home and I am dependent on this connection.
