Disgusging service provider

I have a serious problem for months now with rain. Every month i have to pay and they disconnect me. And now it has become a norm every whn my account is up to date or even in advance they have to find a way of disconnecting me and it always affect my job. I called them yesterday evening i see that they are about to cut me off explained to them that o have alresdy paid on the 31 March, they promised to reconnect me yet am sitting here without any internet then im now forced to go to the office. I am very frustated about this can i please get a permanent solution not temporary as they used to. Because am sure ny now Hello Peter knows me yet nothing gets resolved.
