Handed over to SCS

After endless communication between myself and Momentum with Lancet Laboratories to amend my account in order for their payment to be processed from Momentum, they NEVER send the amendment and they CONSTANTLY delay progress for this account to be settled! Momentum and I are ALWAYS the ones trying to follow up with Lancet and they NEVER seem to help enough to the point where this matter can be closed! All we need is for Lancet to amend the tariff code they used to the accepted and authorised code of Momentums requirement for the test that was done and payment will be processed! One day they say they CAN amend it, the next day they say they CANT amend it, THEN the next day they say they CAN and WILL amend it but then they never do!! I do not understand why such a simple request is taking nearly a year to resolve and instead of assisting like they say they will, I now received a demand letter from their collections agent!!! Unacceptable!!!
