Bad service, poor company!!!!!

I took out a policy with momentum 4 months ago. i paid the first 2 months. I then i had a problem with my bank account and premiums never go out for 2 months which is fine i knew i wasnt covered, now that its sorted, i called in and told them please debit me, i have enough funds, they say my policy is cancelled, they tried debiting 4 times and that is momentum policy for cancellation, which i was never told about!!!! if i did know, i would of made arrangements to pay, but to add to this i called in so many times asking for banking details to make payments, <br> they say momentum doesnt do that. Spoke to Ben from retention yesterday to help reinstate policy, he said he will call back but no help or cover so far.<br> <br> Must i fight with a company to debit me and get my policy on track!!!!!! pathetic!!!!
