Dissapointed by multichoice customer service

Last week I received a call from on Air-TV which I found out that they are working with multichoice in supplying their customers with explora decoders, they ******* me into believing I can get a price lock of R278 a month with subscription included. When I called mutlichoice to confirm they denied it and said it was a lie but they did confirm that they are working with on Air-TV. The agent I spoke to said she won't be able to help me with any cancellation with on air-tv but offered to ask one of the agent working with price lock to contact me and also advised me to put my account with multichoice on hold to prevent my account to be debited twice, then once I cancel with on air-tv I can call back to reinstate to which I did today (30/10/2019) but to my surprise my account was already flagged as unpaid and effective from the 1st of November 2019 my account is going to be discontinued. I'm very disappointed after I have been nothing but a loyal customer to multichoice all these years that they can treat me like this.
