Shocking service

Received call from Vodacom to upgrade tablet. Had query on upgrade, called 082111, referred me to service department, got disconnected, dialed again, was referred to Sales Department (had to dial twice again), Martin at Sales referred me to Upgrade Department and Tembiso referred me to a *** where phone was answered by Mutual something or other! Dialed 082111 again to find out who this company is and where they got my details, lady listened to me and then without a word, transferred me to the After Sales Department (Tato) who could not assist and also couldn't provide me with contact details where to log a compliant on the shocking service received. Dailed 082111 again and an still holding. I have been on the phone for an hour and highly upset with the absolute disregard Vodacom staff has for my time and secondly, I want to know whether I was upgraded by Vocacom, or a third party and lastly, if Vodacom, why can the Call centre not resolve the issue instead of referring me from pillar to post?
