No school backpack

I bought 2 volkano Orthopeadic 27L trolley backpacks for my 2 daughters for scool. I received it on 22 Dec. 2022. The trolly handle of my grade 2 child broke out of the slot. She does not put a lot of things in and have a separate lunch bag and is very neat and does not carry the bag on the trolly handle. I sent it back to takealot 3 April 2023. They said it is not something wrong with the bag it was broken by wear and tear. I can not see that. July my grade 4 childs trolly handle broke the same spot. With a 2 Year warrenty I am not getting anything. I WOULD NOT RECOMMEND THIS BAG TO ANYONE. I wanted it for the comfort of their padded back and good name and quality. NOT AT ALL. I am very disappointed.
