I filed my self assessment in January and was owed a sum as a refund due to over paying my tax on account the previous year. I have followed the links in my account to give my bank details, passed the security stuff and got a submission reference. On checking back after a few days there is no mention of the refund or submission reference and again I am told to 'click here to claim your tax refund to your bank account' - did it all again and got another Submission reference. Waited a week - nothing. Went online to check again - same thing. No mention anywhere of the refund or submission reference / progress / update - nothing....and again I am told to 'click here to claim your tax refund to your bank account' - so guess what I did it again and got another Submission reference etc. We are now coming to the end of April - I now have 14 Submission references since January for the same thing from HMRC saying we have received and are processing then it just goes back too square 1???? I have also been ringing HMRC daily for over 4 weeks - they never answer the phone??? Or it just cuts off. Can anyone help me please I really need my money back and I just cannot get anywhere with getting thru to HMRC. TIA
