Return on damaged goods received with bad attitude and poor customer service

In June 2017 i boight a boot at Woolworths stores in Baywest Mall, in November 2017 the front of the boot tore open and I decided to return it as I am not even a person that walks alot, i drive most of the time and only wear boots in winter...I felt ****** and was not prepared to buy another pair next year after having spent so mich money thinking that im investing on good quality. Unfortunately for me, i failed to keep the receipt/slip because I have never been one to keep slips especially of a stpre i trust and have shoped in for almost all my life and has always delivered on good quality anf the one time, the very firat time i experienced failure on the promised quality "difference", I was treated like an unreasonable customer complaining about nonesense or taking chances. On arrival at the store i explained that I do not have the slip to the purchace and apologised, not once did a manager come to attend to the matter , let alone the cashier apologising for my experience. What stuck out for me the most was the attitude i received from the staff, the cashier assisting me named Ash(something-i cannot recall the full name) bjt she told me the boot has no value (Specified R0.00)on their system, she went away and came back saying the manager has agreed to refund me R294 as that is the last price before the lowest price of R50. I asked if that was the final decision considering i bought the boot for R799, she called another cashier (an african lady, at this point i believe she was fed up by my questions which were polite and not irate) so i assumed she felt the need to bring someone who spoke the same vanack as me IsiXhosa come in and speak to me , the lady arrived with attitude pointing and said "as you can READ the policy on the wall it sais no slip no return unless you can go find the slip we will refund you" i felt so undervalued as a loyal customer that shops at the store for myself and my family, the store best known for delivering on quality yet here i was receiving such poor service. They gave me the R294 gift card and off i went feeling like an asshole-literally!! I am so disappointed that no one even cared to acknowledge that i was not at fault here, my only fail was to trust a store and not keeping a slip.
