VODACOM A NO GO

I have had contracts with Vodacom for the past 13 years and my mom had a contact for me before that. I have always been with them. I am very upset! They are a disappointment. 4 years ago we cancelled my husbands contract as I had a 2 contract on my name. We had so much trouble cancelling the contract that came to an end and ended up reversing and stopping all Debit orders. When he wanted to get another contract for my daughter, they rejected him due to owing for a contract we had cancelled many times. Now the same happened again. I called to cancel 1 contract in May 2019 as I could have upgraded in Feb 2019. We do not use the number at all for the past year. They then notified me the contract will end only in July 2019. Last Debit order 6/7/19. I agreed to that and on the 9th of July I called again to confirm about the last payment and that the contract is now closed. Just to be told it only end in Sept 2019. I wasn't happy and said that I have time dates etc of previous call and I will reverse cancel all Debit orders following. He said he spoke to supervisor that agreed that last debit order was 6/7/19 and contract is closed. I receive an email today with an invoice due for 31/7/19. Where I call Vodacom again just to hear that my last Debit order is 31/7/19. I ask to speak to some1 that I can complain to. Just to be put on hold and the call ended. I WILL never refer some1 to Vodacom again and I will not pay another sent. Will change all my accounts a of today to another service provider!!!
