Pathetic service with no joy!

I went to a dentist last year,when I came home I scanned my claim and sent it through to your claims department!Trusting that you are capable enough to read and pay claims.I followed up,which upon they told me they can't read the practice numbet, which is BS!I sent it through again,suddenly they had a soul that could see it.This year 2015,the dentist phoned me, telling me that I must pay,YOU DIDN'T!I phoned the claims dept. just to hear they couldn't see the practise nr and didn't pay!After they told me last year they can see it the 2nd time!I sent through proof that I did sent it through in 2014.And there was enough money in my savings to pay!After 7 times phoning,ENLARGING the prsctise nr,they said they can see it!Just to hear this morning that I APPARENTLY didn't submit the claim last year,and it has expired!I will NOT leave it here.My sister is in the media industry,I want an aswert TODAY that capable people,and not half wits,are wirking there,and my claim WILL be psid,The fault is YOURS!I also contacted a lawyer,and you will pay with cost IF YOU PREFER GOING TO COURT.Your choice!
