This company pretends to be in business in the UK, but they are in fact located in Bloomington, Ind. USA. The address shown in Milton Keynes is simply a Mailbox and the telephone number re-directs calls to Bloomington. My own experience was that, after placing an order I cancelled it 3 days later and was promised in several E-Mails that my money would be refunded. In fact a second payment was debited from my bank account one month later and I am still waiting for the refund. On researching the internet I discovered that this company is only one of many subsidiaries of Author Solutions and they all have an extremely poor reputation.
