TECHNICIAN WHO DOESN'T SHOW UP TWICE FOR SERVICE APPOINTMENT ... DISGUSTING SERVICE ... NO RESPONSE TO EMAILS ALSO ABT THIS

I am disgusted that I have to post the bad service here. I have been a client for many years...never missed paying a premium...I asked for a service to be done on my alarm (to make sure everything is still working as it should). A lady set up a appointment in December sometime...appointment for 9am...after waiting all day, I get a call from the technician to say he won't make it that because he is too busy with other work (this was 24th December, it was a Thursday) but that he promised he would come on Monday 28th and that he would call me first thing to tell me exactly what time he is coming so he doesn't waste my time again...come Monday...after 5pm I thought it was okay to assume he'd forgotten about me AGAIN??? no call to cancel...just didn't pitch up...think his name is Jonathan. I sent in a complaint in email about three times since then about this as I need the service to be done to ensure my safety of my home....National Security is supposed to protect me but it seems they are only okay with taking my monthly premiums and not delivering the service I deserve. The email confirmation reference / ticket number on my last email to them is 29415 hence I know they have received my complaint. Disgusting service...hopefully this helps move things along...or I should find a provider who appreciates a paying client more.
