I bought 8 books in November, last year and 3 in December. They promised to deliver it in 5-20 days. I wrote them a lot of times telling I didn't receive my parcels and they just refunded me for 2 books (they told me the address was wrong, but it was not). As I checked the books are not in the post office in my country, I asked this week (February) my refund. The just refunded the 3 books I bought in December (it seems that they never send me them) and for the others (the 6 books I bought 3 months ago), they told they will not refund me (145,07 pounds) unless they receive them back. I need the books, but as I didn't received it, I need my money back. I had a big loss because of the delay in my work that depends on these books. Do a favor to yourself: never buy from this shop. Don't trust them.
