Horrible customer service

I went for a operation in April this year. There was a balance on the account which is luckily covered by my Gap Cover. They advised me that they need a detailed statement from Medihelp in order to process the claim.

I requested a detailed statement on 11/08 from Medihelp and even provided them with a document (From Medihelp) that the Gap Cover 3rd party had to send to me as Medihelp cannot provide me with this document (Even through it's their own document) - It's now been more than a month's calls and emails back and forth with Medihelp and I'm still not able to provide the necessary documents for my Gap Cover claim. It has been an absolute nightmare just to get a simple statement from my medical aid!
