Disgusting service

So let's start this ridiculous episode once again. Iasjed very nicely to be assisted,but now I'm complaining as people at vodacom clearly cannot do a simple thing and just want to make money out of there clients. I am in the UK and due to the epidemic that THE WORLD is having I am unable to get back to SA. My cell number *** was up for renewal,but I cannot call as my phone is not on roaming . I have tried numerous times to get through but to no avail. I need this contract no to be cancell with immediate effect. When I tried this before, I got asked what is the cell number which i had given them. What sort of contract was this, I cant help as I have never ever received an invoice for one of my contract that I have with vodacom for over the past 15 years or more. I have 4 contracts with you yet you can't seem to assist me with this simple request. What sort of business are you running. I NEED THIS CONTRACT CLOSED WITH IMMEDIATE EFFECT
