Madness

I have switched to a new internet provider since last Friday and till now I have not used that provider's line to go on to the net. I have been constantly calling them and asking them to fix the line or cable and yes, they did come over to TRY to fix it. But to no extent did any of these fixing helped my cable worked.
Let me give u a overview of what they did.
On Monday, i called them and old them about the cable problem. They said that they will send someone over the next day to fix it. So be it. On Tuesday, that repairman came at around 7 when they said they will come at 5. Never mind then, better late than never rite. After he went through all sorts of check, he said and concluded that the port is overloaded and they need to change a new port.
Since I am living in an apartment and the port is located on the roof and they need the key to get on the roof while the key can only be taken from a certain someone during a short period of time for example 12 till 2pm. They say they will try to get the key and put the portal the next day and would come again around 5pm.
The next day, around 6 they came and guess what? He came in just to tell me that they do not have the key and can't do anything. And next he said goodbye!
The next day i called over and asked with a little anger what is going on and they said that everything will be done on the next day (Friday) and that they couldn't do anything today.
When I asked if the cable would be working or not after installing a new portal they said yes. Then today I called early in the morning to give them some pressure and they ensure me their repairman will come around 5pm to install it.At 5pm when I called over they told me that the people are installing it and asked me to wait for half an hour and the cable would be working. I asked what if it doesn't work. She confidently told me that it will be. Fine, I trusted her. After half an hour I tried to go online but was once finding myself facing the screen full with anger.
I called the company again and ask what was going on and this time I was really mad, all she ask was when are you free tomorrow, we will send a repairman over as we have no idea what is wrong with the cable. I was so angry that I just kept scolding her. But she just repeatedly told me to wait till tomorrow for the repairman to come.
If it was on a normal school day when there is not festival coming soon I would have been more patient but now Chinese New Year Eve is tomorrow night and I still do not have my internet with me which renders me unable to use the web to call back and have a dinner with my family which this year my sister is back from Australia. That is what pisses me the most!!!
I really want to kill now !!!
