Not upholding a manufacturers guarantee policy

I purchased my daughter's school shoes (buccaneer) on 29/12/2018 at the Ackermans Kenilworth Centre, this to avoid the school rush and we all know that there was no school for a further 2 weeks. The straps of both her shoes broke and i returned it today to the store that i purchased it, the store manager which i doubt was the manager or clearly still needed training or just fresh out of training was called, i explained to her my reason for returning the shoes the cashier replies that the store only has a 6 month return policy as the shoe as bought in 2018, clearly forgetting to calculate months and they require grade 12 to be a cashier. The store manager then states that there is a policy for all school shoes and only the sole is guaranteed and not the upper, she sends someone to fetch me a shoe to show me the policy tagged on the shoe, only this is not the make that i am returning, which i point out to her and she says that policy is on all the makes of school shoes, also continuously asking me if i understand, where i had to ask her do you think i do not understand english? because it seemed to that way. She then explained that there is nothing she could do and i asked her for the head office number as her explanation did not make sense. As i left the store i went to check for myself if the buccaneer manufactured school shoe has this policy and to my utter dismay it did not, but it had a guarantee from buccaneer that you could return the shoe if you were dissatisfied to the store you purchased it WHO WOULD GLADLY REPLACE THEM FREE OF CHARGE. At this point i called the store manager and asked what part of buccaneer's policy she did not understand and why on this make of school shoe there was no policy about just the sole being guaranteed. She said she will have to forward my complaint to her manager and will get back to me. she took a photo of the shoes, slip and i had to write my number on a piece of paper. I called the head office, was put through to a call centre agent, who said that it would take 24 to 48 hours to resolve/give me feedback regarding my complaint. So what does my child where to school now, as i had to explain to the principal as to why she is not wearing the school attire? Ackerman's will make that i will not buy a product by that manufacturer again!
