Hi, my boiler stopped during the night, no heating and no hot water. It is a Vaillant.

January, minus 3 degrees outside. The phone never stops.
A Monday in January, 7:45 am. In forty minutes you have already missed six calls, you were at the first customer of the week.
Six families with no heating who call elsewhere. By the time you are back, the line has gone cold: they found someone else, or they are angry.
You are over a boiler, bleeding a circuit. The phone buzzes five times in ten minutes.
Four new customers who think you are swamped. They try once, twice, three times, then they call a competitor. You just lost four weeks of revenue.
In summer, it is the maintenance contracts and the new boiler quotes that come in.
But you are in training, on holiday, or simply at a customer’s. You miss annual contracts, exactly the revenue that smooths out your business.
85 % of callers never call back when no one answers. 62 % contact a competitor right after.
