UK Solicitor needed – Prevention of Winding Up Petition

UK company director facing a winding-up threat from my former accountants over a £3,000 invoice. I don’t dispute the debt in principle but:

The service (filing of 2 years accounts) was not completed

They disengaged without offering a structured payment plan & suddenly demanded payment in full. where as payment used to be £200 a month. In addition an unexpected £1,000 invoice was raised after disengagement. They handed these invoices to debt collectors, i paid £1,000 and offered to clear the balance in 4 - 6 weeks but the debt collectors didn't agree. So I paid £1,000 on the spot.
My company is solvent and trading, with clear receivables and only incured temporary cash flow issues largely contributed by these accountants.

I believe this may be an abuse of process and insolvency law under Rule 7.5(1) of the Insolvency Rules 2016.

I need a solicitor to:

Draft and send a formal legal response

Prevent or delay any winding-up action ; Possibly file a court injunction if needed

Negotiate a settlement or structured repayment

Please respond if you’re SRA-regulated and experienced in debt disputes or insolvency defence. Urgent matter.
