Vodacom are *****'s, stay away from them

Hi there. I have been having an ongoing issue with Vodacom and Elite mobile which apparently is a preferred supplier to Vodacom for the last 6 months. I called to cancel my contract as my term was over, the retentions department offered me a suitable package and convinced me not to cancel, this was on the 16th September 2020. From then to now I have sent numerous emails, numerous escalations to managers and to date they do not resolve the issue. So basically they false promised me a package which I have in writing from Vodacom and they each month fail to activate the allocations and bill me for it. I have requested them to cancel as they cannot warrant what they promised and to no avail. They are ******** and none of the team leaders or managers take responsibility to have this resolved once and for all. Absolutely disgusting from such a huge corporate
