On 1st December 2020, I ordered the Cambridge companion to the Cello from infinite books via Amazon Marketplace. The money was deducted from my bank account on the 2nd of December. By the 18th of December the book has not arrived after being told that it should be with me by the 7th of December. I informed Amazon on the 18th of December that I had not received the book, and fair play to Amazon, Amazon immediately refunded my money. I never received an apology for the non-delivery directly from Infinite Books. Very sloppy service- if you can call it service. Probably best to call it zero service. I suggest that nobody buys any books from them. I challenge them to contact me directly to apologise. They should be easily able to find out who I am because I have given the title of the book above.
