Vodacom - Disgusting Service Received!

As per my previous complaint I ordered an upgrade on the 9/8/2020 and again on the 21/8/2020 due to Vodacom not been able to help me with my order. I went into a store today to try and do the upgrade there due to me still not receiving my phone 6 days later and when I called in I was told by a rude Johan that he is unable to assist me to cancel the upgrade as it was with the courier. When asked if he will accept waiting for a delivery for 3 weeks he was rude and refused to answer me instead scream over my voice and tell me he couldn't do anything. I am so disgusted with Vodacom and never had I imagined that they will be so unprofessional. Is this how they treat their customers? If so this is appalling! I wasn't able to sort this out even after all this. The stores told me to contact the usual no's where the useless staff cant do what they are paid for. So Vodacom does it again.. Useless and Pathetic !!!
