Unprofessional useless *********** No service

I called vodacom to cancelled a contract on 30 November 2020. The consultant took all my details convinced me to take another contract which I declined thereafter advised cancellation done and I would receive an sms. A whole 4 days have passed ...no sms. I called again today at 13h11... consultant once again tried to talk me onto another contract which I told her do not as I am not interested 14 minutes later after verifying my details she then advised she doesn't see my cancellation. I asked her to check gave her the telephone number I called from as well as the time and she put the phone down. What shocking unprofessional service. Firstly that we have to contact a call centre only to receive an unprofessional *********** person to deal with your account. Despite the bad poor service..they only want to convince you to take another contract. No way will I take another contract rather to a different service providerm
