Playing management decision ping pong at client's expense.

Bought basket ball rims in July 2022. In Jan 2022 one of the rims snap on the matter rim. I take the rim back to the store as it is still under warrantee so it can be replaced. The gent attending (22 Jan 2013) to my issue at the store tells me I have to bring the whole structure as they can't replace the rim only and have to replace the whole structure. After some lengthy argument with me trying to convincing it is not necessary to replace the whole rim structure, I give up and leave to go collect the whole structure for the rim. By the time I get back the gent who said I should go fetch the whole structure has left the store already and now I have to be helped by another person who tells me she can't process the replacement as some key deciding managers are not available. I ask her to contact the decision makers over the phone and request for their assistance to process the replacement. She after some ten minutes tells me she has tried everything and unfortunately can't help me so I have to return on Monday(23 Jan 2013). I then leave the rim and its whole pole structure and backboard with her and ask her to call me when the replacement rim is ready for me to collect. Today around 11h00 she phones me to inform me her management says they are only going to replace the broken part! I find this extremely offensive and inconveniencing to me. Decathlon must stop wasting my time and replace the whole rim structure as they had insisted when I had brought only the broken part... but they said I must being the whole rim structure because they have to replace it all.
