slow internet connection

I haven't made any post for almost 3 days due to sluggish internet connection. I tried to call a technical support from my Internet Service Provider to ask for any feedbacks on why our internet connection was too slow. But they just give me some nonsense answer or they just don't wanna admit that the problem was on there side. The internet connection was pretty bad that time, it's like a roller coaster ride sometimes you got a high speed then it drops into low connection. Imagine having a 512 kbps connection in just a matter of minutes it will drop to 6.6 kbps. 

I called them again and finally they admit that the problem was on there side. They told me that our connection is being monitored by there technical team and they experienced a network problem in our area. It came into my mind that some Internet Service Providers are not honest with there clients or maybe they just protecting there business. But it would be too unfair for clients like us who is hopping that they will give us the right answer. I know there is no stable networks even large Internet Service Providers encountered this kind of problem what I don't like is that they've lied and tried to insist that everything is fine at there side.

Internet connection was finally restore the day after and all I can say is that they solve the problem in a very long period. I just hope that our connection will be stable.
