Foschini Gateway poor service

I visited Foschini Gateway today to return a perfume (narciso eau de parfum) which I purchased between November/December 2018 and Jan 2019 When I bought the perfume and opened it a week later it was absolutely rotten. I returned it and they smelled it agreed and replaced it. I opened the new bottle in the shop and it was perfect. I have many perfumes and had got to know the ladies there personally. Two months ago the perfume spray stopped working. I was away and now that I am back have decided to take bottle in. The bottle is a cream colour and you cannot see into it even if you hold it up to the light. The branch manager said the bottle was empty which I disagreed with as she had no way of knowing this. I have used approx one-third of the perfume and not even half of it. They refused to take it back and said that Area manager and the cosmetics Manager declined my request. They said i could leave the bottle and they would send it away etc. I declined and said they should break the bottle open and if it is empty I would accept but if not they needed to replace it or credit or something. They refused to do that. I am angry and disappointed at such poor service from Foschini. I want this resolved. I am 59 yrs of age and would not be running around with an empty bottle of perfume to be replaced. That is absurd and foolish. The new branch manager at Foschini Gateway is not people-friendly. Do these people realize they are in SALES and not medicine? Your assistance would be appreciated.
