Terrible customer service/Claim taking way to long

I will never in a million years put my money into Alexandre Forbes again if I can help it. I've been waiting for over two months for my claim to be paid out. I've been phoning them twice a week every week sins the claim was processed. First they submitted my wrong tax number. Then they got the correct tax number but neglected to submit it. After I phoned them 10days later to ask how far we are they told me that they neglected to submit my tax number. There was no communication from there side again I had to phone to find out that it had been submitted and then I have been phoning with promises that this had been submitted and payment would be made. A month later and empty promises I'm still waiting. I'm furious after sitting on the phone for 30minutes and being transferred left right and centre to speak to a manager, I eventually get to speak to her and tell her I'm busy writing a report on Halo Peter so she phones the accounts department and boom all of a sudden they going to make a payment today. When I say to her this situation is \********"that I need to threaten before they do something about the situation"
