DEBITSCREDITS.CO.UK reviews

Hi just want to warn people do not use or trust this company like others i was quoted a fee for my end of yr tax return and when a bloke called naz put the work in for me he then text me 30 mins later saying he wantèd extta money on top of the agreed price of £150 to do he actually wanted another £150 for how he described extra work put in which was 30 mins of work and the icing on the cake is that he calculated my yr earnings 3 k above what i actually earnt and i didn't realise until i got another accountant on board and he bought this up to me , so in my opinion please avoid as never heard of an accountant that obviously cant add up numbers correctly or was it a scam 2 try to get more money from me the is the question but do not trust this bloke
