I have received my tax calculation and requested my claim online which will be paid via Bacs, however my tax calculations have also been sent to a fraudulent company called Hawkshaw, I have never signed up with this company but I have heard that they have the ability to take tax refunds from cheques, but I need to know if they can take my online tax refund payment also now that they have my tax calculations? If so then this is serious and I need HMRC to get rid of them from account as I tried ringing HMRC but no answer and I have tried to call and email Hawkshaw ltd but no answer either so this frustrating.
