Blue Label Contract Cancellation not going through

My wife bought airtime from Edgars for R77 per month through Vodacom. Then they changed from Vodacom to Blue Label Connect without our consent. Since then we experience multiple problems. We bought her a new phone and it just doesn't want to work with Blue Label Connect. We have cancelled this contract last year and on the 6 June 2021; she received and sms to confirm that. Her sim card got damaged and she cannot do a sim swop until the contract has been cancelled. She has a Vodacom number and Vodacom keeps on saying that Blue Label Connect has not cancelled the contract. We have contact them and we left messages for them to contact us back but they are not responding at all. We are pensioners and don't have the means to keep on calling them. This is a catch 22, Vodacom says it is not cancelled and Blue Label Connect says it is cancelled. Can anyone please contact me to sort out this mess??? It will be highly appreciated
