Infinity knows they have inferior Routers!

We app**** for a Fibre line with Infinity and they Installed a 50Mb up, 50Mb down line. It worked great! But only downstairs. We lived in a duplex house and had NO reception in the upstairs area. I contacted them and they advised that I must put an "Extra" system in that will cover upstairs also. This system was almost R5000. I initially asked the installation technician if this Router will cover the upstairs area and he confirmed it would, But it did NOT. I cancelled my contract with them and found out 6 months later that they handed me over for R23000! I will NOT recommend anybody to have dealings with Infinity as they are ******! They knew the system doesn't cater for duplexes, but STILL installed it, just to sell me the BIG R5000 system. ******!!!!
