Poor service and incompetence

I called in November 2018 to upgrade my speed from 4mbps to 10mbps. I was put on a new contract and not offered a device, and no luck of getting out of something that i did not request for. This year i called in to query a new device as more often than not my current device switches off and needs to be reset. I called in 3/10/2019 at 11:33 and spoke to Nofundo who advised that i have not been migrated to a new package and it is just a device that was ordered. I finally receive my decide today, then receive an sms advising me that my device is ready to be used and the service will be billed pro rata from the 10/04/2019. So I call in to find out why i got this sms, the lady i spoke to first at 12:59 was very unprofessional and when i asked to speak to the team leader she said she is on lunch. I asked to speak to the manager and she says she is on another call. So i ask to hold and she cuts me off. I call in again and i am asked for my ID number so someone can call me back. I have done this previously and no one called me back. I am so tired of fighting with Telkom, I just wish they can relieve me of this contract because I pay for a service that is not efficient and it frustrates me. I need someone to resolve this urgently.
