Dont listen to Customer Needs

I have been struggling with discovery vitality for a few days now. They advertised and emailed since last year about their new option they have this year with regards to gyming for free. I have sent an email requesting feedback and finally on the 4th of January got feedback. Although it didnt answer mty actual question, i found the information, but emailed them again asking more information as they didnt answer it. I also asked that they would phone me. On the 5th of January i got another email explaining me with complete different information, but still no phone call. I emailed them again, as the phones are never picked up even after being on the line waiting for 25minutes. I explained and showed them the evidence that the previous information they gave me said something different and once again requested a supervisor to phone me. Then this afternoon i got another email explaining me once again different information but still no phone call. Now the only option i have is to log this on this site in the hope that a manager or supervisor will call me to explain and fix the problem. This is the second time in 2 months that i have to refer to hello peter. Please help me!!!
