Terrible terrible terrible experience with vodacom

Terrible. I have been trying for months on end to cancel my contract, which has expired, but i am still billed every month and now my line is not working. I have migrated my one line in October 2024 but i am still paying for the previous contract. Now it is reflecting on my credit score. I was on the phone with them for more than an hour today and i have proof of everything. My problem has supposedly been escalated but my problem is not resolved. One of the many consultants i spoke with today told me to "pay up and request a credit later" if i want my line to be unblocked. Just to be clear i am paying the amount that the first consultated gave me into their acc every month since Novemeber, but i refuse to pay for the services on my bill that should have been cancelled. I am fead up and tired of phoning and talking to consultants that will not and don't want to help. Vodacom is the worst service provider ever.
