Poor customer service.

I have never received such poor customer service such as the one from Blingstallation. My decoder has sent an error message,which is due to faulty installation. I called them on Thursday the 3rd of May 2018 and informed them of this problem. They assured me that they will send one of their technicians and put me on their "urgency list"to this day no one has been sent. I have been calling them,they keep sending me from pillar to post. Apparently the technician who is "supposed" to come assist me today is off sick. What kind of business are they running that when one technician gets sick then all things fall apart. You would think they will have stand bys' for such unforseen circumstances. I asked to speak to one of the managers, I was made to hold for 10 minutes and then I was cut off. This is really unacceptable as I paid for this service and this is what I get. It is appalling how they claim that we are valuable customers and then treat us like trash. Where is value for money in all of this?
