Better Planet Books Refuses to deliver the books I paid for, won't give refund. Scam Internet

I purchased my books last month. It's been nearly a month and they've yet to arrive despite me paying for 2-5 day shipping. I emailed them asking when I should expect them near the end of the fifth day and got a tracking number that didn't work. I emailed them mentioning it didn't work, no response. I email them twice more over the next two weeks, no response.

I get a couple books, neither of which are what I ordered. They weren't even in the subject I needed! I emailed them about them sending the wrong books and stating that I'm about to issue a chargeback if I continue getting ignored. That's when they email me back, when their money is on the line. I send the books back, as they ask, and they agreed to send me the correct books with the 2-5 day shipping free.

It's been two weeks since they told me they'll send the correct books and I've still not gotten these books. I've emailed them three times asking when I should expect them, no answer. When I sent an email demanding a refund, that's when they respond (note how they only respond, and promptly if I may add, when money is on the line). Nope, they won't issue a refund despite it being in their 30 day return policy and not getting what I purchased. I will be issuing a chargeback now, as I warned them twice I would do if this continued.

Do NOT use this scam of a "service".
