discovery provides incorrect information

On the 16 or 17th of september i called discovery call centre to enquire how many free consults i have left for the year.clearly the consultant told me 3 visits.my son went to the doc and a few days later i did but to a different doctor. I still have one visit left when i visited my doctor on monday this week i was called back to say discovery denied the claim stating i have no funds left.i find this very odd and all discovery i get told that my son and i visited the same doctor and this was claimed on the 25th of september Dr Ballim .information was incorrect as i do not visit that doctor .i called the doctor arguing with them regarding the information which was given to me by discoverys call centre since then i called the call centre 4 times but it take 8 mins and then i have to hang up ..listen to your voice conversations they are recorded and please pay my doctor as i still have a visit left for the year. I pay my premiums and i dont expect to receive such poor service and incorrect information
