VERY BAD CUSTOMER SERVICE

So my internet is of since Saturday (Its Tuesday now) so I have Fiber through CG Communication's - but they work through Openserve on my Fiber. I've complaint to my Tec from CG Communications, and he told me that I have to wait until Monday, there is nothing he can do on a Saturday (witch made me angry immediately) So waited until Monday, yet nothing - then the problem is with Home Connect and then with open serve. Its now Tuesday, STILL NO INTERNET!!! And the excuses comes in from Openserve. I never experienced this from them, but come on, 4 days without the internet YOU PAID FOR! and month end the bill will look the same although you didn't use the internet
