No cancellation has been done!

After a lot of frustration, phone calls went into Vodacom branch Highveld Mall Witbank, my cancellation as requested are still not done. On the 10th April 2018 I phoned cancellation department to cancel my contract ********** 216, we are relocating and don't need that contract, I'm working from my phone(S8 plus) the gentleman send me a premature cancellation Form, which I signed off done payment of R295.81 as on pmc Form. I struggled with my vodacom Email and manage toe send it through on the 11 April 2018,I followed up with a call 10h35 and spoke to Annett and she confirmed they received the docs as requested for the cancellation, which I emailed to ********** said it will be processed. Again on the 16th April I spoke to Sipho and he said accounts will take the number of my invoice due to cancellation no need to worry. After follow up on cancellation I get the same answers. Friday 22nd June I received a call for a good upgrade on this very same number and the gentleman told me on his system nothing show any cancellation. Due to the fact of relocation to Western Cape and funerals I can not phone every day nor once a week to make sure Vodacom do their work properly, this is unexceptable that they still charge me R110 after I've paid up this contract. At this stage I want to cancel al my contracts with Vodacom due to lack of service and follow up the whole time to prevent inconvenience like this but whether you phone or go into town to their shops nothing has been done but they don't delay any payments deductible from my account. This is not acceptable for me.
