Lack of client centricity

I recently purchased few items online, however some of the dresses bought did not fit me as well as I thought they would so i attempted to return them to the store today.

Experience received was absolutely appalling, firstly the lady was very dismissive and showed no interest to assist, she told me a lengthy story of how online and stores have their separate budgets and me returning these items and not exchanging instead is of an inconvenience to them as i did not purchase in store therefore impacting their budget.

Not really sure what this has to do with me as a customer, please tell me where im supposed to return these items if the store is this unwilling?

She further told me to go and print out the receipt/invoice before they can assist? Do your stores not have printers? I do have an option to download this on my phone and show the store assistant however this was not an option given to me or suggested but more to go to an internet Cafe and print out?

If this is what I have to go through to merely return 3 things in store why are online orders not coming with receipts so that I dont need to jump through hoops to return things at the store?

This has been an absolute waste of my time and money and I need someone to attend to it urgently.

I have been your client for years and absolutely enjoy your online shopping experience and it's efficiency. However please train your store consultants on what good client experience is and looks like.
