Very bad service

I received a call Saturday 11/07/2020 to advise that I m due for upgrade. I accepted upgrade for Huawei P30 lite for R330. Today I called Vodacom cancellation department spoke to Timothy Govender he told me that he cannot assist me in cancelling must visit the nearest store for cancellation, then I requested to speak to the manager as it didn't make sense as to why should I have to go to the shop to cancel he said his manager Hlengiwe advised him to tell me that . I requested to speak to the Hlengiwe but well my call was transferred back to the line and the was dropped. when I call the number back the number I cannot get through is engaged. After this contract I will never use Vodacom again the service is very bad.
