O2 guys are COMPLETELLY crazy.
I ordered an internet for 600kč per month.

I refused every upsell, because 600 was over a reasonable limit. (and because none of them had ANY value to me)

After they removed all of the upsells, the final price is 300 per month.

Why would you include upsells into the price? I could have chosen even faster overkill internet plan, if I knew the real price? Are they actually retarded?
