Cancelation of 24 month contract

I called Vodacom retentions department to cancel my 24 month contract on numerous occasions and no one there seems to assist. On the 26.01.2022, I spoke to one of your consultants (lady) in the retentions department @ about 5pm. I explained the reason as to why I needed to cancel my 24 months contract which took about 15 - 20 minutes trying to retain me from canceling the contract. However I was asked to be put on hold for no reason. I was literally put on hold for about (45 Minutes) if not more( please do listen to call recording) . The lady never explained the reason for long hold, I had to ask why and was it right that I was put on hold for so long. All was said I'm sorry🙄 it's the system is slow. Now that makes me wonder! How does she not follow-up with me for such a long time. This type of service is unacceptable!!! This is called call avoidence. Makes me wonder why I should even continue with Vodacom. No TCF… I was told I will receive an sms/ email confirmation that I will get an instruction to cancel.
