Bad service and always connection issues, service requests not done properly or on time

What was the reason for moving all of Nepic's client base to supersonic, ever since this happened i have being having so many connection issues, the service is so bad, i hold on the line for miuntes and hours, on whatsapp i sent a message at 10:30am from my personal number and still havent been attended to now at 3pm, i sent a message from my work number at 1:30pm and an agent attend to the later request 1st and i asked me one question to which i responded to immediately and nothing after that, still no agent or response to my call from 10:30am, how do the sla's or whatever work?

Very bad service - Wish they never made the decision for nepic clients to move as i had the best and great service from nepic and never faced issues with connections or service like this and now.

Requested for my line to be upgraded and they keep telling me its done yet i can see its not done and confirmed with frogfoot its not done too but keep getting told the request was sent and have to keep doing speed tests and justify. unacceptable - thinking of looking elsewhere and moving as this was just done and decision made between the comanies.
