Mindless games, no customer service

I once had an MTN online profile. MTN have decided, for no apparent reason, that everybody has to create a new one. But they've made the process into either a nightmare or a joke. I can't decide which. Endless blurred photos in a mindless game of "click the one with a tiny piece of a car/street/shop." Then an error message saying I should contact the administrator. BUT NO INDICATION ANYWHERE OF HOW TO REACH THIS IMAGINARY ADMINISTRATOR. Well done on building the worst, most amateur website of the century.
