Bad customer services

I have contacted Paypal about a ********** company. I bought steel shelves and they sent me small plastic *******. Paypal insisted I must return stuff back to them and submit proof and then only will Paypal refund me. Bought the shelves for $29. Cost to return $45. Value of plastic ******* is $1. No logic. I have also contacted Paypal on numerous emails and submitted proof that company has also done this to numerous other people. Now Paypal refuses to refund me because I didn't submit proof of stuff that was returned. Paypal claims to protect us against ********** customers and failed to protect me. PAYPAL IS USELESS!!!!
