Was with Rogers for over 10 years. Service was great, rarely experience outages (maybe once every 2 years and they were often for less than a hour) and had NO congestion whatsoever.
Then they introduced caps and throttling. Service slowly went downhill from there as I live in a household with heavy downloaders. It wasn't so bad when they capped the overages at $25 a month but around last year they uncapped the overages and lowered further lowered the cap on their Extreme Plus Service. Sometimes I ended up paying over $150 a month even though I was receiving a 40% discount on the base price.
Used a Moto Surfboard DOCSIS 2.0 modem that I purchased outright from them when they were doing that for around 75.
Made the switch to TekSavvy this month thinking the grass would be greener without caps but TekSavvy is nowhere near as reliable (long and frequent outages) and congestion is horrible.
Would come back if they would raise cap and reinstate my discount. My experience with Rogers is nowhere near as bad as some others have described.
