Misinterpreting information

My husband have taken a package with multiChoice, then since we're the one who use it at home he then calls multiChoice to add my name and identify to have access to this account, i then move to family package options and also include remote on my package because the consultant gave me discount if i can include explora remove, i was paying R329 since it was month to month contract that was taken online and the calls were recorded. Only find out yesterday that i was paying paying more than R400 since the remote offer expired without informing when and it will expire when i took this package or send me email or even sms or calls but the contract does not expire since it was offered if i can include the remote. I need the company to listen to their recording regarding conversation between consultant and the client.
