On hold to cancel contract for 45 minutes

I was on hold for over 45 minutes after dialling *** to cancel my Vodacom contracts. These contracts have long expired and on each attempt to cancel them, I have either been put on hold or have not been able to get through to the number specified. Is this a ploy by Vodacom to frustrate their clients into NOT cancelling their contracts? Furthermore I logged onto the website and started a chat with a consultant asking them if there is anything else I can do and this consultant, although pointing that I could email [Email Removed] when I asked what do I need to actually email, her responses were so generic it was sad. For future reference if a customer asks what do I need to email, please inform the consultants to NOT retype out the email address and telephone number to call because, as a customer, in my opinion, you tend to lose all faith in the consultant if they are at that level of incompetence. Again I am still stuck with these 2 contracts and hopefully in this lifetime I will be able to cancel them by some miraclr
