REFUND NIGHTMARE!!!!!

I have now been struggling for almost 4 months to get refunded for the NIP1 test I underwent for my high risk pregnancy. I have been calling the call center non stop with incompotant service and emails gets a no-reply generalized response and no further response about the query.. Every time I call to find out why it is yet again rejected, I get a new excuse as to why. Everytime it is something else. For weeks even the PathCare representative have been struggling to get information out of them. Worst of all is, that I received pre-authorization to have this test done as per my high risk pregnancy care plan. Gems is just adding more stress onto an already high risk pregnancy which is going to cost them more if something happens or goes wrong. I am considering legal action as this comes down to *****. Approves you for a certain procedure but when push comes to shove finds every excuse in the book not to refund a claim. This is unacceptible. I have been a member for many years almost never claimed any big amounts but when you do they do not forfill their side of the agreement. I am on Emerald and expect service for what I pay for. I MUST BE REFUNDED FOR A PROCEDURE I WAS PRE-APPROVED FOR BY GEMS.
