Mess
Oddly enough at our Xmas reunion in 2017 a colleague told us this mess was about to happen.
He blamed the Spaniards, and a boss who thought the sun shone from his proverbial Spanish IT team. Who in reality had no idea of the difference between elbow and other part of anatomy.
Mystic Meg he told me understood the problems better than said boss.
What could he do? The Spaniard was on a permanent siesta, he would only be rumbled from slumbers when it all went tits up.
So, the problems were known, expdcted, not the magnitude. A few unhappy customers is fine. They cam be fobbed off and ignored. Just like with the whole problem.
