Bad Workmanship with no follow up

In July-17 we reported a burst geyser on my property. Close to 2 weeks later no response, resulted in additional water damage to my property. Having had to deal with more than 20 providers to handle each complication on an ad-hoc basis finally by November-17 most of the work got done. One provider has however left a portion of work undone in addition to various quality issues that need reworking. We’ve contacted the provider over 15 times in the last 3 months have had 8 confirmed appointments the provider never arrived at. The provider will not take our calls. We’ve notified Dial Direct on 4 occasions the last was 26 January 2018 were we escalated to management (Louis Meyer), I followed up 5 &8 February 2018 with management who undertook to follow up, still, no response 26 days later, with management expediting. Over 7 months later in spite of many follow up e-mails, phone calls and requests for action. I've still got significant damage to my property reported and not attended to.
