Vodacom fibre

I am currently trying to cancel the poor Vodacom fibre we have had to go to a new service provider, Vodacom are making it an absolute nightmare. We have done everything on our side they requested, a months notice, etc.. but they still have us up and running and billed us for another month. 25 plus minutes each call with the most useless call center staff!! Proper attitude with all the call center staff as well, they making us feel like the ones at fault! One of them even logged a second cancellation when we had one logged already!! We now have to log another request to get the money they took refunded!! I cant describe how bad they are so never ever use Vodacom Fibre as a service provider!!! Im so angry i feel sick!!
