No feedback, No call back, NO SERVICE DELIVERY!

I've just about had it with momentum! My husband and I both submitted a two pots claim on the 7th March I received mine with no hassles however my husband did not. We made contact 2 weeks later and was told there was a system error and the claim would need to be cancelled and submitted again. We've called in several times after that and were told " IT is busy with it", then "IT has fixed the issue and the claim has been disinvested", then yesterday again "the issue is still with IT". After every call there is a promise that someone would call us back and nobody has we have had to constantly chase you guys to find out what's going on. This is pathetic! And from a so called prestigious company? Psshhh
