Horrible Service and Excess Claim

My wife was in an accident caused by another lady that rammed into her side. First Momentum advised on Body Workshops with all bad reputations, I had to go and find one that had a decent reputation myself. It has now been 8 months and I am still waiting for my excess to be paid back. I had to keep phoning and begging for some answers just to be told "it has been handed over to attorneys" and nothing else. After I got fed up and spoke to the attorneys myself, I was just told they were waiting for information from the 3rd party. 8 Months is rediculous. If I do not get my excess back by the end of the week I will move to another insurer, that is a promise!!
