WORST SHOPPING EXPERIENCE EVER!

I bought a pair of boots recently from Foschini. The boots are very uncomfortable and hard! I went to the Foschini Mimosa Mall branch, where I purchased the boots, on Saturday round noon to return the items and they could not assist me because I am a cash customer. They apparently only have R200 a day in their till. I asked if they can make the return on my debit card (on which I made the purchase) and a staff member told me they could, but that it would take 7 days for the refund to show in my account. I rep**** that I do not have a problem with that, to which another staff member rep**** that I must keep in mind that they can't guarantee the return if I opt for a debit card return. HOW IS THIS POSSIBLE?!? So Foschini, you firstly do not cater for "cash customers" by not having cash in your tills, yet you were happy to accept my cash with no prior warning that I will most likely not be able to return the item. And secondly, if you do not have cash in your till on a Saturday at noon, when will you ever have enough cash in your till??? Do you expect of me to return to your store on a DAILY BASIS to check if you perhaps have enough cash for me to return the items??? Then the best part is that when you telephone Foschini customer care number ***you cannot speak with anyone unless you enter your ID number (which you do not accept because I do not have an account with your store) or my account number (which I do not have because I do not have an account with your store)???? Does your return policy specify that you will most likely not be able to assist with returns if an item is bought with cash?? that a customer must simply wait until you have enough cash in your tills??? Until when must I wait??? MY WORST SHOPPING EXPERIENCE EVER!
