Hello there,
Like Micheal Foo said RM 500 is nothing when you need your website online 24/7. The service charge is normally because of middle man charge. By the way, if your company is comfortable with the 'middle man' services, why ditch him ?
For RM 50 yearly payment ,you can ask him anything you want about the hosting

Cheap right ? IT expert consult is RM 450 per hour.
However, if the middle man actually purchase a really cheap hosting and make a profit out of it, then you should ask him to change hosting. Your payment of RM 500 should give you a better server hosting than normal ones
Thank you,
