This is not acceptable

My car has been to Danmar autobody before (via insurance), & I was impressed by the speed with which they have sorted things out. Not so now. I dropped my car off with them 3 weeks ago 6 August 2015 - & to date, I am apparently waiting for parts. When I dropped my car off, I was assured that the parts would be there by the following week & the damage that required fixing was a quick turnaround. Needless to say, this is the story that I have been told every week since then. Why create the expectation by giving me inaccurate dates by which parts should supposedly have arrived without the cer*****y that they actually will? A day or 2 give or take is one thing, but 3 weeks later - my patience has run out (even if more parts had to be ordered). What's worse is that the branch telephone and email lines have been down, which i understand no one could foresee. However, I have only received updates from Nic-Marie when I have phoned her myself? While she was 'kind' enough to give me a cellphone number on which to reach her, I will not accept being treated with attitude & irritation when I phone for the updates that she doesn't bother to give me herself. I am still a paying customer!
