No Stock Triple jump Spikes

I bought Nike triple jump spikes for my daughter at Nike factory Atterbury, we bought Nike due to the fact the she's having her second pair of running spikes and also few pairs of tekkie's with no problem with Nike's products. But we had a problem with the triple jump spike where it started to come loose where the spikes it self turns in. We then took it back to the shop mentioned above on the 25 February 2023, they had no stock and the daughter had to participate in an event on the 27 February 2023 which the manager then said we can keep it as we put tape around it for us still to use and return it on the 03 March 2023. We went back on 03 March 2023 as that was the time given by the manager to bring it back or we will get no refund. Arriving at the store they still had no stock and due to the fact that my daughter went to the next round she had to participate again the next day 04 March 2023, this time there were a deferent manager which were a lady and she said that its the last day and they can't refund me after this but she will let me use the spikes ( still damaged ) again but then I will have to chose something from the shop for the amount they own me, then I ask the question if I can keep the credit until they get stock and her reply was NO. Why not as it is not my fault that Nike Factory don't have stock and I am not a person that judge a brand by the first incident ( complain ) as Nike did proof to me that its good quality. The lady said I must order online I then said to her these days its not safe to order online and I am not willing to do that. I am not sure if I now need to try a deferent brand as the service from this shop and the way they handled my return and complain because I need new spike but the factory don't have and now they putting me under pressure and I might loose my refund, even after I did reported it on time but unfortunately they never had stock. Why must I loose if they don't have stock they need to keep my credit till they get stock I did return my product with in the factory warranty time therefore why must I now been send up and down and get threatened that I won't be able to return or get a refund after this coming Friday 10 March 2023 and that I'm not allowed to keep it till they get stock again.
