Escalating matter to ombudsman The FIX things consumers are stupid.

I bought a Jacket and pants from the fix on the 8th of September 2022, I did not fit the jacket however i still went ahead and purchased it. This morning the 15th of September i tried wearing the jacket but it didn't fit so i asked my boyfriend to exchange the size for a bigger one. Unfortunately i lost the reciept but the jacket is in good condition, never worn before and it still has a price tag. the consultant at the fix Westgate told my boyfriend they will not do the exchange without the reciept even when the jacket still has a tag. They said there's nothing they can do. So i must just forfeit my R399 that i bought the jacket with. The consultant further said they will not exchange it because they have a new policy after the looting that they will no longer exchange andvrefund without slip even when the clothes were never worn and still have tags on them. My question is where is this policy written? Did they let the consumer know before purchasing their merchandise? I want a document that shows me that policy that i was never made aware of because i will certainly escalate this matter to the ombudsman. The fix must not think consumers are stupid we also know our rights.
