Glue comming loose

I bought a pair of Terrex Adidas tekkies 2weeks ago and they are already comming loose,took it back to the outlet upon wich i had to leeve them there so the tachnical guy can have a look at them,eventualy when i managed to get hold of them i was told to come fetch my tekkies because nothing is wrong with them and i sould continue wearing them for next 6 months and if they become worse then they will inspect and excange or refund me,in 6 months they will tell me that i abused the tekkies thats why so sorry,after telling them im not happy the answer is just ai were sorry like sorry is going to solve my problem that cost me R1000,so im stating that i have only been wearing New Ballance for the past almost 4 and half year and will continue to and that i will never support Adidas or any of their products and will NEVER recomend the brand to anyone ever.
