Its not that bloody hard is it..

Hello all, how are you today?
Well i am yet again a little peeved.
Why you may ask?
I will tell you..my name as you all know is Sara..not Sarah,Sarhara,Sahara or any thing bloody else..so for some reason the bank has changed my name on all correspondance to Sarit..yep Sarit..how they got that i will never know.
I keep changing it back and informing them of the mistake they are making..i have been with this bank for years and years..and for the last 2 they have been calling me Sarit.
I am fed up..small in the grand scheme of things i know..but really annoying .
So from now on when they send me a letter i may just return and say not known at this address..suck on that lollipop.
I could understand if my name was a long one or hard to spell but its 4 flipping letters..and get this when i ring the bank i get told that my name doesn't match the name they have on their records..what!!!!.how can that be i had to take my bloody birth certificate to open it ..so somehow it has got changed.
They have one more chance then its Adios..
It may seem a small thing but its very annoying.
Sorry for moaning but i was given a name and no one has the right to change it..
sara,sarit
