Peutred Service!

I recently visited Jaysons Gas as I usually do. My 9kg Afrox cylinder was weighed in at the entrance, I thereafter proceeded to pay and awaited my cylinder after being told there was still 1kg of gas in it. A few minutes later I was told that they are now draining the gas(the 1 kg I came in with and the gas that was now filled) I was told due to wear and tear my cylinder is now "broken" forget repaired I was told it needs to be replaced. I was absolutely flabbergasted, here I am with a R1300 product that worked perfectly fine an hour before arrival at Jayson's Gas, was perfectly fine when weighed in but now I'm told that they are not disputing that I came in with a working product but there's nothing they can do now that it literally broke whilst in they care. They staff are extremely impolite and unprofessional. I was told by the "manager" that the customer is never right, the same manager who stated that he's not disputing that my item was perfectly fine when I brought it in and he goes on to tell me it's wear and tear. Anyhow I thereafter called the store to speak to the owner, just to be told by an inexperienced worker that I brought in a "broken" cylinder, I was in absolute shock on the call considering I used my gas stove not too long before going to Jayson's and it had absolutely no issues whatsoever. The valve was bent and I could hear the gas leak when they brought my cylinder back to me. They tried repairing it, which doesn't make sense if they did not break my product why were they attempting to repair it? So after an hour plus long wait I was told there isn't anything they could do. I walked in a with a perfect item left with a broken one that no one wants to take liability for. The worse experience ever, if there was an option to select a - star I would definitely choose that, 1 star is clearly too much for Jaysons Gas.
