Pethetic Service

Paid a 50% deposit more than a month ago and gave notice to proceed with installation 2 weeks ago. Installation was supposed to be completed this week but I've had nothing but delays, excuses (if I actually manage get hold of someone at all) and endless issues. Only after posting on FB do I get a call. Do I get an apology or resolution, oh no, I get attitude! So here I am, still waiting and still no timeframe on completion...
