Bad online service from Bash

I received a birthday gift in December from a friend which was aldo sandals that cost around about R1100. After only wearing the sandals for about 2 weeks the sole peeled off. Its been from pillar to post from there. I've been to Aldo store with no luck. The bash return policy is horrible. A courier was sent out to collect the sandals and issued a copy of a waybill. Now bash is asking me to provide the copy which is now misplaced as I wasnt aware I will need to send it back. Bash organized the couriers, shouldn't the couriers be liable to provide the waybill details? I want a refund to end this nightmare.
