Bad service and no client satisfaction

I had submitted a doctor's bill to Gems for claims. I was asked to submit all invoices which I did about 10 times. I have called Gems only to be pushed from pillar to post and being put on hold for more than 20 minutes at a go only for the call to get cancelled. All these telecom communications was at my expense and I have received NO help. I asked to speak to a supervisot only for the lady to reply with 'eish' and put me on hold for 20minutes and then cancelled the call. I called today again only for the same thing to have happened to me. I though we civil servants deserve better care and attention than that. I have still not received any payments to these bills I have paid. It's been more than a month. I have references for all my correspondence with these *********** call center agents. Disgusted at how I was treated.
