Vodacom's Customer Service Team is appalling

On the 22nd of April a Sales consultant called me offering me an upgrade package for a sim only deal where I will get 5GB .I advised the consultant that the package sounded interesting however I was actually looking to downgrade to lower my bill .I suggested that I can take the package only if he cancelled 1 numbers I did not need anymore in my account .he confirmed over the recorded line that he would do so and confirmed my new bill will drop to R603.00 Fast forward 10th of May I recieved my bill and the commitment was not honored

On the 8th of June I spoke to Brian Makhanya adviced him of my story .he then committed to cancel the number off my account as they promised to do so I then requested to speak to a manager Brian's Manager Melicia advised she will call me back so that we can find a way forward and this was on the 10th of June and I still haven't heard from her. I also spoke to Naicker L on the 8th of June still no feedback I was even contacted by the survey team and they also promised to get back to me but nothing I am now paying for a service I requested to cancel I tried my level best to reach out to the Vodacom team but they treat me like i am just a number. I have been sent from pillar to post .I have been transferred to ext numbers that dont work or my call gets cut off Please assist me to get this issue resolved as I do not know what to do anymore. I asked for recordings to escalate this further but there's still no way forward
