Extremely unhappy customer

Edgars doesn't resolve issues of customers. Instead you get blamed. I have 4 pending issues with reference numbers and one declined claim from home protect insurance. I was told that it's was owners carelessness, my helper was cleaning the shower and the glass door came out of rail and broke. I was at work at the time of incident , so how is it my carelessness. This company will close down if you don't address issues. Edgars staff act like they're the owners of business including customers service helpline. May I hear from the superior if they agree with this kind of treatment to customers.
