Poor Customer Service

One the 21st of July I returned a shoe that I bought from Steve Madden Eastgate the service I got unprofessional. I was told the shoe was returned and I’ll get my refund within 24hrs. Up until today I haven’t received any payment or wallet refund. Done a life chat with payjustnow and was advised to contact Steve Madden which I did on the 5th of August spoke to Tumi he advised that after 2 hours refund will be done to the wallet account. On the 6th of August I called Steve Madden advised that my wallet hasn’t been credited yet and the guy advised there’s nothing they can do on their side. I advised I should publish them for me to get assisted the guy advised I can go ahead.
