Poor sevice & false advertising

I recently got a 3mbs line from amobia, while the installation was professional 10 days later I got lovely email from the telling me I will now be throttled to 0.5mbs. Firstly after logging calls with them from day 1 I have never got my 3mbs at max 2.4mbs and less. Secondly no where in the contract does it explain where and when I will be throttled just wham there you go. Yesterday after many calls I seemed to be back up to my amazing speed of 2.4 mbs ( not 3mbs for what I am paying for) suprise suprise today I am back to less than 0.5mbs. After phoning the support 5 hours later no response. .<br> As normal. .<br> Amobia what the he'll am I paying for??? My advice to others is never to use them full of empty promises and blatant false advertising... extremely dissapointed... uncapped? Please....I will definitely be making sure everyone I know in the IT industry for which I work never uses this poor excuse of a isp
