Bad service by Momentum Health

Since joining the scheme last year November, i have had endless problems. They are not committed to customer service and don't get back to a person. I have to keep following up.They are quick to take my money but cannot committ to dealing with there clients. Its been 4 months dealing with one query and still to date it has not been resolved. I am absolutely appauled by there service levels. I am so sorry I ever joined this scheme. Never have I experienced such bad service.
