Vodacom Wonderbooom Junction

I don't like to complain about things but I had the worst experience with Vodacom at Wonderboom Junction Yesterday (2020.05.28). My wifi is due for an upgrade so I called the shop where I got the contract and they told me that I should go into the store as they cant do the upgrade over the phone so I left work early got there about 30 minutes before they close and waited outside because their door was closed, the shop was very quiet, another bloke that was also waiting outside (unattended) he was there before me I told him to go in when one of the customers came out (covid vibes) the staff didn't attend us at all it seemed like they didn't want to help us, long story short 17:02 one of the staff came outside and recons they cant help me the shop is closed now so I told him if I was inside they would have had to help me and he just said well I wasn't inside and told me to come back another time. I stood outside thinking I was considerate because of covid and he just refused to help me with a 5 min upgrade and this after I stood behind a closed door for more that 30 minutes. This is absolutely pathetic I really want to put a stop order on my debit order as they don't give a flying emotion about customers. Another thing, I couldn't register to the Vodacom app because this wifi number I had was still registered to someone else's name and I have had this contract for almost 2 years now. I don't know about other stores but I wanted to punch this guy there and then because of his arrogance. I am really furious because of this. Again I don't like to complain but I support their business and this is the thanks a customer gets? Pathetic!!!!!
