Returning online orders

Worst online return with Edgars, I went to return a dress and when I got there I was told I needed to provide a slip but unfortunately l didn't have a receipt because you're online order doesn't come with a printed reciept and I couldnt find the one they sent via the email so I was just told to go back and look for it they weren't even communicating or assisting on how to go about getting a receipt for an online order. They were just dismissive! Eventually I got to send an email to edgars the next day and got the receipt and then everything went well and then I had ordered another order that had legit items i needed to return, so I went to legit to return the items because they were not suitable when I got to legit I was told they needed a printed slip and I told them I had a receipt on my email so I can just send it to them but their computers only work for business emails only and nothing customer-related so I had to go and print out my slip but there was loadshedding so there was no way I was gonna print out in that area so I had to come back another day with the printed receipt and it took more than 20 minutes just to get everything sorted. I've bought so many times from Edgar's online but never had to return anything before but this situation is just making me never want to buy from Edgar's online ever again because they make it seem like they're doing you a favour by helping you return things you got from them that are not suitable for you. Cashiers just leave you unattended and are not helpful in anyway!
