Starhub 切斷 my service

Lately I found out my internet and cable TV all cannot access. So I called up Starhub. They told me my service is suspended. I was shocked and tried to find out why. They told me I have outstanding bill. However, it is found that I have paid up 3 weeks ago! Then they still got the cheek to tell me there is a reconnecting fee of $15! 好搞笑﹗Of course I refused and 和他們講道理。Finally, they gave in to waive off. Terrible!
