Pathetic service for my claim

I am disapointed with the service from Medihelp, I was admitted in April in hospital and was told medical aid wont pay the MRI as they have to wait for non disclosure department to do investigations as i am new with the medical aid,that was fine with me as i called medihelp and queried whether will i be paid back my money if i paid for the scan after they are done with their investigations and they said yes i will be refunded. I paid R8200.00 to get the scan done as i was in so much pain but guess what two months later i am still waiting for medihelp to refund me and each time i call i am being told that my Dr has not send the questionnaire back. After being discharged from the hospital i contacted medihelp to check the investigations they said my Dr has not sent the questionnaire, i called the Dr and she said she hasn't received anything from medihelp and she gave me her email address,i called medihelp and only to find out they sent the email to the incorrect email address then i gave them the correct email address. I waited to hear from them and nothing from them, I sent a claim email last month the 03.05.2018 and on the 23.05.2018 i got a claim number : ********** 02003 for the claim and i thought a solution to my problem is happening only to find out now that i was actually wrong. The previous week on the 08.06.18 i called Medihelp to find out about the claim and again i was told they still waiting for the questionnaire from the Dr which i was not aware of as medihelp does not even bother to give me an update about the Dr not submitting the questionnaire back to them so i asked the lady i was talking to who said her name is Bonita that can she ask the non disclosure department to send me an email stating the dates they sent my Dr the questionnaire form and the email address they have used so that i can make a follow up with my Dr,guess what up until today i am still waiting for that email and I called today and it seems i am just wasting my cellphone units for nothing as i am not getting anything positive. Can someone who knows what he is employed for get to the point of this matter? I am tired of calling Medihelp and not getting anything, i mean R 8200.00 is a lot to me if its nothing to the call center people who i talk to almost weekly.
