******* Paypal policies

I bought a device from an international online Website www.bamlisa.com. The incorrect device was delivered. I contacted Bamlisa to have this corrected. They didn't respond. As I paid for device using PayPal I contact PayPal to have this corrected. Paypal insist I either get re-imbused less 1/4 of what I paid, or I pay for return shipping fees and only get re-imbursed original amount of what I paid if device returned correctly. As such I am now liable for expensive shipping fees to return device due to merchant fault irrespective. This is against the SA consumer law and as such this practice is *******.
