Query: Quality is lacking

I have an old pair of these shoes that I have loved for a long time, but needed to replace. I ordered this pair and was very disappointed in the quality. I have only worn these shoes perhaps a dozen times and the sole is already coming apart. They also have this weird squeak with every step that I take. I will be replacing these, but will not purchase another Keds shoe.
