Tax Credit Over payment, Debt Colleaction Agency !!! Please Help !!!

Hi All,

I am new to this forum, having read lots of thread, I believe this forum is really helpful. I will be grateful if someone can give me the correct information.

I have a tax credit over payment since 2011 which HMRC was collection through my Tax credit award until I have started a second job in September 2016. Once I notified about my second job, the HMRC has stopped my Tax credit Award payment. Have not heard anything until I Have received a NOTICE TO PAY letter in June 2017. As soon as I received that letter, I have called the HMRC payment helpline and set up the Direct Debit to repay the pver payment amount by monthly instalment.

Everything was fine, then I have received a letter yesterday from a Debt Collection Agency stated that HMRC has appointed them to collect the over payment amount.However, I have already agreed to pay this over payment amount HMRC by Direct Debit.

I have called HMRC this morning asked for explanation, they said it was a system error. HMRC gave me a reference number to give it to Debt collection Agency.

Then I called the debt collection agency and gave that reference number and explained the situation. They said they will put my case as pending until they have received the confirmation from HMRC. Once confirmed by HMRC, they will close my case. Although, I have asked them to send a confirmation once the case is closed, but they said they are not going to send any confirmation. I need to give them a call to find it out.

Can anyone please advice me is there anything else I can do? And is this whole situation going to affect my credit rating anyway?

Thanks for reading and thanks in advance for your help.
