No Response!

I have a 3 year extended maintenance plan with 360 +. At first I thought my policy was held with Liquid Capital, so I called them, then I was told to phone SA Warranties, which I did, they told me I needed to contact 360+, I was bounced around from one person to another during the course of 24 minutes. I spoke to a lady by the name of Lizelle and opted to hold for an available agent, but everyone was busy. I was on hold for 10 minutes but no agent ever became available to take my call. Eventually, I left my number so that someone could call me back... This was 3 weeks ago and I'm still waiting! I have emailed them... No response. I just called them again, was on hold for 14 minutes and then my call was cut off! Seriously ***!!! I need authorization from 360+ for my annual service, but I suspect there may be a problem with my policy however, I can't get through to anyone to resolve this matter. I'm so disgusted with their lack of customer care.
