Unable to cancel Vodacom fibre account due to practically NO CUSTOMER SERVICE

I have been trying to cancel my fibre account since December 2018. I phoned Vodacom in December 2018 to cancel my fibre account (which expired on the 31st of December 2018) to ensure it does not roll over month to month, however I was told I cannot cancel my fibre account over the phone and I have to send a cancellation email to ********** ********** I sent a cancellation email, a follow up on the cancellation email and phoned them AGAIN today to cancel my fibre account but it is still not cancelled. When I phoned today I was put through to 3 different departments and nobody could assist me. While transferring to another department, they answered and put down the phone without even talking to me. I don't think ANYONE at Vodacom knows what they are doing. This is RIDICULOUS !!! Not only do they waste your time and money, but you have to continually contact them and follow up or nothing is done.
