Terrible servic

On Wednesday 1/11/2023 I had a tube fitted in my rear motorcycle tyre. I bought the tube from the same business. On the 4/11/2023 I went for a ride only to discover that the rear wheel was flat. On 06/11/2023 I took my wheel to tazman motorcycles and they removed the tube and inspected it and informed me that the tube had bulges and a hole on the inner part of the tube. I then took the tube back to Yamaha ,only to be met with an arrogant manager who did not want to give a refund as I did not have a receipt, even though the workshop manager informed me that they can print out a receipt. She then told me she’s going to charge me a handling fee as that was their policy. Their policy states that after 14 days a 20% handling fee will be charged. The manager gave me 80% of what I paid for the tube and I did not get my 50 rand back that I paid for fitting. Thank you.
