Exorbitant fees charged by Heathbridge Claim Management/mymps

I started my GP Practice in Feb 2017.I subscribed to health bridge. They offered a flat fee of 3% with no subscription fee or minimum claim fee. In less than 2 years the fees have gone up 120%. Now they charge a subscription fee and a minimum claim fee. For those doctors that are starting off practice, I do not recommend using Healthbridge as the fees can cripple a fledgling practice. They strategy is to offer a low initial commision fee to attract you and thereafter increase your fees exponentially.
