Vodacom - No after sales service!

I have 4 contracts with Vodacom (1 main and 3 data lines). I have been trying to cancel 2 of the data lines for more than 6 months now without any luck. I was contacted in December for an upgrade on my main contract and I was told that my total cost on this specific contract will reduce from R 1 819 pm to R 1 579 pm, including a new handset, as this was part of a Black Friday Special. I specifically asked the agent if this will apply immediately as I was not sure when my contract reached the 2 year mark. He confirmed that this will be the case. He also upgraded the 1 data line that I wanted to keep, which was done. I was given the cancellations department's contact details to cancel the other 2 data lines which I am not using.

My issues are as follows: 1. The 2 data lines that should have been cancelled has still not been cancelled (ref: ***). This costs me R 328 pm for something I can't use. As mentioned, I have been trying to cancel these contracts for more than 6 months. 2. My total bill for all 4 contracts was usually R 2 320 pm. With the upgraded contract and the lines that should have been cancelled, my new monthly cost should have been R 1 728 pm. However, my debit order this month was R 3 584.86 !!!! Apparently my old phone was not paid off yet (not sure when this will happen)... But even if I'm still paying for the old phone, my bill should have been R 2 398. I have sent numerous e-mails to the so called Customer Care department without any feedback. The first complain was sent on the 14th of February 2022. Vodacom doesn't care about their customers. They are quick to sell something over the phone, but their after sales service sucks. Contacting the call center is a waste of time - after waiting forever to get through, the person on the other side has no idea what is going on. I really hope this review reaches them and that they will contact me to sort this out, because nothing else so far has worked. A difference of R 1 856 pm might be small for Vodacom, but in real world for the average person like myself, this makes a huge difference. I will never again refer someone to Vodacom.
