Mr Price - shocking MrP App. no help with return

This site won't allow me to give NO Stars or 1 star, but that's my rating. Here we go again... I have been trying to return an item purchased via the Mr Price app. It is a memory card (unopened). I have had a response from a Precious via email and since then, ****all feedback. I don't swear but the service is so shocking it warrants you hear my frustration.

Please assist!!!!
