Vodacom Cancellation from abroad

I have emigrated abroad and cancelled my Vodacom Contract before leaving South Africa in June 2019 , which was I must say for a large company like Vodacom quite frustrating . I contacted their cancellation department probably over 20 times. Cutting a long story short, received the cancellation quote. I then paid the cancellation fee of 8k and then had to contact the cancellation department another 20 times to confirm an email address to send confirmation of the sign cancellation form and proof of payment for the cancellation fee. . The email address on the cancellation form was not going through to Vodacom which I found strange. Eventually managed to get my email through and I now thought this was sorted. It’s now Dec 2019 and I am still getting bills from Vodacom. And now it’s impossible to get Vodacom cancellation from Abroad. And Vodacom general customer care cannot help me.This is ******ion from Vodacom
