Shocking customer Service

I was in contact with cellc for an upgrade, I had a query for them to better the upgrade, this was in the beginning of June 2020,everytime I was told they will escalated my query and get back to me, I'm still waiting for feedback. This morning 16th july I called again and was assisted by Clive that could not really help me when asking to speak to a supervisor, I was told there was no supervisor and the supervisor starts at 13h00,i told Clive to get the supervisor to call me when he gets in the supervisor is Allen. I told Clive not to cancel my contract till I speak to the supervisor, he rudly put the call down and then I received a SMS saying my contract cancelation has been processed, I'm really not sure what is happening by CellC these days.
