Makro Brakpan gas refilling station doesn't deliver and management is unhelpful

Makro Brakpan gas refill station runs a very interesting side to the business. I took my Afrox gas bottle to be refilled as they have a statement online that Makro refills gas. As it was just after 5pm and I already had to shower in cold water for two days the representative told me they don't refill gas, I would have to exchange my bottle. I was give an ugly rusty bottle as an exchange but in desperation I had to take it as I needed a hot shower. I asked the representative that when I come next time if I could get my Afrox bottle back as it was property he told me no problem. Today I went to do exactly that now that my gas has finished and I was told that he couldn't do that, that is not how it works. As anyone knows when you purchase a gas bottle you have to pay a huge deposit. I have had that bottle for years and 19kg Afrox are hard to find. Basically, not only did Makro made me pay for the full gas bottle of gas they also ****** me of the deposit that they get back into their pockets when they return the Afrox bottle. I spoke to two managers who went to 'investigate' but still nothing was resolved and I had to take the rusty green bottle back and go to a local hardware store who gladly exchanged it for at least a nicer looking bottle. Do not trust Makro gas refill stations, rather go to a normal gas refilling point or even a hardware store, it may be a little bit more but they won't ***** from you.
