Poor customer service

I bought a shower unit from this business. When installing the shower one of the glass panels exploded into small pieces. They claimed the glass was shatter proof which proved not to be the case.

I call on a daily basis and been told that their glass experts will contact me. This is pathetic customer service. I have been reduced to begging
