Unprofessional behaviour from agent

Unprofessional behaviour from agent. 1. Gave out information about order to a unrelated 3rd party. 2. 6 months later and the router that was part of the offer had still not bren delivered 3. Over 10 phone calls and tickets and case numbers abd over 5 hours of being on hold, and nobody had returned my calls. 4. No case numbers were attended to 5. Fibre line was broken. Was never issued with a ticket number. Vumatel will not fix the line without the ticket number 6. Agent made 3 calls to me harrassing me to stay connected with them. The 1 call was 30 minutes long. Also brough up personal information raising the death of my father and son. He also threatened if I took on a big company like MTN, I would be blacklisted.
