Momentum Car Insurance Sucks

What a shame!!! We sent our car for repair from last few weeks but there is no call back from anyone today in the morning when i called them to enquire about it they said they will follow up with repair work we never received any quotation or anything it was just approved without our consent then i asked them to speak to manager that lady doesn't even know how to speak to humans we told them we want our car back as soon as possible she said she wont give it back to us what kind of behavior is this? While doing marketing you talk about big things and give false claims about claim being done in 24 hours but it is more than 24 days but they are still going to take more than 15 working days we pay regularly without fail we don't eat food but we pay our premiums and this is what we get in return can someone look into this as even senior managements are having an ugly attitude towards customer services what a shame MOMENTUM cant you find better people for senior posts
