This is a bit of an odd one and I would be grateful if anyone can tell me how they would proceed. Back in February I wanted to pursue constructive dismissal against my former employer and contacted an employment lawyer. They offered me help with my grievance and negotiations for a settlement agreement for a fixed sum of £2.7k including VAT. Then I changed my mind about this, for various reasons, and I never submitted the grievance or pursued my claim. I talked this through with my lawyer and she said if I cancelled she would give me some money back to recognise not all of the work went ahead.
I left my employer in May and started a new job in June. The lawyer offered me £500 + VAT refund by email which I accepted, although had been hoping for more. I chased her in August as I still hadn't heard anything more and she apologised and asked for my bank details which I provided. Since then nothing- no sign of the money and my emails are not replied to.
I have obviously had to write off £2k+ and have put this down to a very expensive lesson in the need to raise a grievance before you hand in your notice, but the small refund would have been some consolation. Do I have the right to this money as it was offered by email? Is there anything I can do to get it? I am aware that this is a fancy London lawyer and I have no legal expertise at all.
