Pathetic sales department

After calling the sales department for 8 times in a row and the keep being cut off every time. I requested a migration on my number *** and the upgrade department did the migration on ***. When I speak to the last consultant he says he can do nothing I must call cancelations. I expect vodacom to go back and listen to the voice recording on the initial request and fix this mess as the upgrade was done wrong not by me but by your people so dont tell me to call cancellations to fix it as this was your ***** up. Please call me back to sort this out now. I want to speak to a team leader now.
