Vodacom Bad customer service

I upgraded one off my numbers to a big data deal via the call centre. Was informed contract would be valid 1 May 2020. On enquiring on the 1 May 2020, i was told because delivery had not taken place, it would only be valid on the 1 Jun 2020. I cancelled the upgrade request and the consultant send a note to Ram couriers to return the parcel. I subsequently have taken out another contract. I phoned around the 22 May to load a cancellation on the number and was informed that the upgrade was still pending as the parcel was delivered. I informed the consultant that i did not receive any delivery and I also instructed RAM to return the parcel to them. But the original consultant did not ever bother to follow up, after the i requested cancellation on the upgrade. However the consultant said i need to sort this out with RAM and this was between me and them. So I did Vodacom work for them and Ram located this parcel and returned it to Vodacom on the 29 may 2020. I have been trying to phone Vodacom since the 29 may 2020 and you either get cut off after 4 min of holding on. The cancellation number just cuts the call, I have requested call back, but have had no response. Vodacom is one sided, the only thing there consultants can do is put notes on system, they don't follow through to ensure customers request are completed.
