ISP frustration!

I'm so pissed at my ISP and i'm going to tell you why. I have internet connection at home since the 4th of October so the only net i get is from public places, on October 6 i made contract with a ISP and they said it would take 15 days(yeah that's right) for them to install the fiber optics in my apartment... fine at least i'll have a awesome stable internet connection.

After 15 miserable days i was so looking forward to having internet again and... they didn't show up and i got no calls from their IT department, on the next they i called them and they said something was not right (duuhh) so they asked their IT department to call me when ASAP.

Two days later and still no call so i when to a nearby ISP store, they said the contract was not created correctly and i should talk directly to the same store where i signed it so they can correct it, there i went again to the other store this time i heard another story, according to them everything was done right and the installation should have been done in the 21st, so the store is going contact the IT department and again tell them to call me...

I'm stuck in this loop where no one wants to be blamed and still no internet connection... So that is why i am pissed and why i haven't been online much thus the lack of posts this month.
