Vodacom is a ****: It's not even poor service

I was offered an upgrade contract by vodacom towards the end of September, but I cancelled the contract within the 14 day period, come month end vodacom had not cancelled the contract. I called them to cancel again, the consultant said they have put a cancellation request again because there was an error, but I tell you to this day it has not bn cancelled and everytime I follow up I get a new reference number because the previous one is not done. I even tried for their assistance from their twitter account but they just keep telling to wait its still in process. Now yesterday they sent an sms about balance contract 15 has been activated I called them to understand what it was, consultant said their system had an error creating a contract with a cellphone and the bill is about R1400, this something that I didn't take out, I actually explained I m struggling to cancel a contract, now vodacom is saying I took out a cellpohone contract. She said they were gonna reverse that its an error from their side, and I should wait for 3 days and I have heard that before to no avail.. So vodacom machines just automatically select a person and create a contract that you didn't take and you're billed😒😒🤔. This is not on, they are just creating one problem on top the other. This network is **** something needs to be done, and anyone who has not taken anything from Vodacom yet, do yourself a favour and stay away.
