ASR Accountancy Ltd

I worked as self employed for 4 months and asked Mr Ayhan Koya their service. At the end of this period i mailed them to close my self employed account with hmrc. They did not do it and i received a fine 2 years after for 300 pound. When i wrote them to ask rectify my position and close my account (after they forgot to do it at time) I was asked 200 pound for it even though it was clearly a miss from their side . I managed to convince the HMRC calling them to cancel the fine and i close the account by myself. They are very unprofessional, i suggest to avoid using their service.
