Starting off with bad service....

If this is how it starts?? Placed my order a week ago, confirmed installation for the 1st of March a week ago, then yesterday they moved it to today, today they all of a sudden have the address wrong and cannot install, they delivered the router to this adres, just pulling up their shoulders and say anew order have been placed and they will call me within the next week to arrange for installation, in the meanwhile I cannot work from my home and loosing business each day that I don't have internet, mobile data too slow, they just don't care...
