Havaianas bad shoe quality

From today I can conclude that Havaianas flops are BAD QUALITY. Last year my fiancé and I bought our first pair of flops at Havaianas store in Sandton City. My flops broke about 7 months later and when I went back to the store to report the shoes I was told that my guarantee has expired and therefore they cannot assist me. I bought a second pair of shoes on the spot thinking that it might have been my fault the shoes broke so easily. Few months later my fiancé’s shoes broke exactly the same way mine did and today (5 months later from the date of purchase) my second pair broke as well. No clearly the problem is with the quality of the shoes! My shoes are still under guarantee but now I’m not even interested in owning another pair of Havaianas shoes the way I’m so disappointed by their quality.
