Bad service

I have been speaking to Telkom for two months now and am not getting any assistance. Today I called I was transfered to Phumeza who placed me on hold while attending her personal things. There after she ended the call without providing service after she had placed me on hold hold for more than 30 minutes. This is unacceptable inappropriate behavior. I want to cancel my contract because telkom is billing me for what was not agreed upon. When I upgraded my contact I was called by a consultant mislead me because he offered me a contract for R190 which consists of 40 gigs for night and day. To my surprise am being billed around R600 per month. Shocking is the fact that when I went to lenz telkom to complain they reduced the voice limit to R1. But now am shocked that I owe yet R600 which I don't understand why. Telkom is ********* for deviating from the the contract. I must say the service has dropped am not sure if this is due to employees working from home and they struggle to balance work and personal life. I will like to terminate my account with immediate effect since am not getting any assistance. I will be canceling my debit order as my last resort to resolve this issue. Am very disappointed with the service I have received
