Bad service

I didn't know an upgrade or canceling a contract with vodacom can be such a headache. I was due for an upgrade in November 2024 and I called vodacom, I was told my upgrade was processed and my router was going to be delivered within 5-7 working days and that didn't happen, I was told my upgrade didn't go through so we have to start the process again and I agreed. I waited until January and they still didn't deliver and I'm expected to pay an inflated amount from what I used to pay for my contract😡
