Worst online purchase experience

Good Day

I bought few items from Edgars online and decided to return some to your store at Edgars West street in Durban as per your return policy for online purchases.When I got there I was asked how I paid for the items,I told the lady it was with a debit card I was told you didn't have cash because it was still early in the morning which I understand,I was told to come to take the items with me and come back at 12pm which was an inconvenience because I had errands to run but still I understood.When I came back at 12:30pm I was told to forward my receipt to your email address,I didn't even have data because I use wifi at home and honestly felt had i been informed of this when I first came to your store I would have done it when I got to my apartment but I bought data and forwarded th4 email.The lady still had to go print it out then when she came back she told me that on her side it shows that I paid with pay just now,I then told her I used my bank card she asked me to go to my app and show her my bank statement.I honestly felt this was a lot for me and besides my app was suspended so I had to go to the bank for assistance as it wasn't allowing me to unsuspend it online as most of us know that capitec app always has issues.I explained to her that the PNJ is a tracking number for my delivery she insisted that I paid using Pay just now.To cut the long story short she told me she can't assist me with a refund if I don't produce proof that I paid using my bank account.The line was getting long and some customers coupd hear our conversation,I hate anything that causes people to stare at me so I left the store and your items there as well,this is very *********** from your staff members and an inconvenience on my side.I buy online from toiletries to clothes,furniture etc and I've never experienced this from any of the stores
