Director of single director/shareholder company took maternity leave, and the company paid SMP. Company requested advance funding. HMRC asked some questions, which I answered, but then simply went silent. I called them and was told there was no intention to pay the advance funding or to respond to my letters. I then sent in a complaint but have had no response. I therefore called the number on the HMRC web site and was referred to two other numbers, the second of which had a recorded message telling me they were too busy to take calls. I have already asked the Agent Account Manager for help, to no avail.
I understand I can only go to the adjudicator when I have "completed tier one and tier two of the organisation's own complaints procedure, and have received a final response from them".
Can anyone recommend what to do next? The only thing I can think of is to ask my MP to refer it to the Parliamentary Ombudsman.
