Misled by Blue Label Communications into a contract

So I received a call from blue label connect earlier last year. Stating as a valued customer of Edgars I am being presented with a gift package which will allow me to buy airtime and 3gb of data at discounted prices. Stated I will receive a sms with a link where I can purchase the same through Edgars. Agreed to receive it, but I've Never received the sms, and after a year I realised that there is some money debited from my Edgars account for sms and airtime/ data. I went to edgars to complain on Friday 12 June 2020, hey contacted blue label via some international call center and they agreed to cancel but not to refund as they need to get the call recording first to confirm if i did not agree to this madness. Today 15 June 2020 they called and played me a recording. The recording mentioned its a gift for a wonderful edgars customer like myself etc. and that ill be sent an sms to link and login and if i want to use the services the benefits can be purchased via the edgars account. Never a mention that they will debit my account whether i use the services or not. When I explained to the consultant that called me with a recording she said I should have asked the consultant that sold me the deal. How do i ask questions to someone who was going to send me login details for me basically to decide if i was going to use their services or not before i get charged? The fact that I don't remember ever receiving an sms or login to their site to activate this deal made me relax with a clear conscience that i was not owing anyone anything. The call was misleading in that it was mentioned that I would receive a link (never did). It places one under the impression that once you receive the link you will be able to buy the products at the discounted prices. Not be charged on one’s Edgars account even when you never activated the benefits! I will be laying a complaint at the credit ombudsman, and will take this as far as needed. I need to get the refund and also to stop other people from being misled in the same way! The phone call received and what was stated is totally different to the outcome.
