Thou shall receive RIP-off if thou contract comes to an end

I called in at the beginning of October (1.10.2019) to give notice as my contract comes to an end the end of October to cancel my entire contract with 2 phones. Unfortunately staff who were listening to the #yannos or whatever did not submit my full request, instead only cancelled 1 number and then I was left with the other which was the free phone and airtime by the way. I queried twice in November (7th and 20th) and requested them to listen 2 my call where I have given that instruction after (this is whilst I'm still being deducted for something I did not want and I did not even use the airtime after November). In December i spoke to an alleged Supervisor, named Ady, whom I repeated my frustrated story with and was promised to get feedback by the end of business, that was as on 10:26am 10.12.2019. As per usual, they disappointed again like Mabena and on the 20.12.2019 I was debited yet again.

I have been a loyal customer for more then 10 years and having been on contract with them for the last 5 years but this is what I have to go through since I did not want to upgrade or take a new contract.

I'm writing this with absolute faith that no one in the vodacom complaints or whatever will even respond but with even poorer signal as of late I'm porting along with my whole family at the end of this month.
