Meghbela Broadband — Fluctuate connections and poor speed

I, santanu banerjee, a customer of meghbela isp. My user name is santanu_mtcn. I have been paying the money for 60 mbps speed but i am not getting that actually... Connection is very poor and fluctuating... Almost everyday morning i can see there is no internet connection... After communicating with them they give excuses like.. Their fiber optic cable has torn... But all are #... They give this excuse in ever occasion... Inspire of taking the plan of 60 mbps speed, i only get a speed of 5-15 mbps... And highest speed that i have experienced 28 mbps.in fact after calling they sometime misbehave.
