about 3 weeks ago i made our first claim for tax cedits,after not hearing anything for a while i gave them a call to check it had been received,the lady was very nice and congratulated me as my claim had been accepted and then began to reel off all these different amounts of money,to be honest i didnt really understand what she was on about but anyway she assured me that a sum of x amount of pounds would be paid in on the 15th.so i rang the bank yesterday to check and they have paid in over double what she told me!the annoying thing is i have not received any award notices so i dont know were i stand.of course this had to happen on a weekend,when their shut !has this ever happened to anyone else and will i have to pay it back?
