Exceptionally disappointed - No Service

I submitted a claim to Discovery in January due to Storm damage in the December holidays. Firstly, I had to continually follow-up with them as no-one contacted me to tell me my claim progress, eventually a service provider was assigned to repair damages. After they came through I contacted Discovery to inform them that I was not happy with the quality of service and that they have not come back to finish the job. I have followed up with Discovery about 4 times to find out what has happened, each time I was promised, they would phone me back and investigate. We are now in April. NO ONE FROM DISCOVERY HAS EVER PHONED ME BACK!!! Also it still has not been completed. I am now so fustrated as I do not know what to do in order for Discovery to take me or my claim seriously.<br> <br> SHOCKING!!!! I just want my claim finished properly.
