Singnet is going down

Recently my internet connection is going bonkers, have been facing this problem for a few weeks.... and yet nothing can be done to solve this issue... Been calling the helpdesk but it seems like there is no appropriate solution to this problem... My mood is also dampen by this issue as my daily life in the net is affected greatly... i can't do things properly without the usage of internet... Furthermore when i doing research, it is worst... You know how long it took me to load a website like this... i think if i didn't keep refreshing it.. It will take around 1 min.... Freaking useless... Will solve this problem with singet this weekend.. Before i flare up and sue them....
