Poor Service - South Surrey BC

I've been a Shaw customer for over a decade. Last week my wife and I moved in to our brand new condo in South Surrey. We moved only 8 blocks from where we used to live in White Rock. Service in White Rock was always consistent and fast, but since the move to our new home the downstream throughput fluctuates massively from 4mbps up to 18 mbps..not quite the high speed 25 package that I'm on. Upstream however is very consistent around 2.5 to 2.75 mbps. Tonight I called support and sat on hold for 45 minutes and spoke to a rather apathetic person who said that the node is congested, there is nothing that they can do, and my only options at this time are to "downgrade to a lower speed package" or "change to another provider"...not exactly what I was hoping to hear as I work from home frequently and require a stable connection. I asked if he had any timeframe for correcting the congestion issues and was told that he has no idea, could be 6 months to a year...that is just fantastic. Anyone else in South Surrey experiencing similar issues or is it just me?
