Bad service

On the 23rd of Feb our company loaded a fault , this morning a guy from the technical phoned asked about the problem and said he is coming out that was 11:04 (he phoned from ***) , then at 15:35 I received a sms saying our fault has been restored but no-one was here , I phoned the call center and then the lady I spoke with told me she doesn't know who the tech was , now how is that possible they must keep track of this how they know who's doing what where? And if this one that is getting a salary every month is even doing his job!! And how can I now report him if no-one knows who the tech was!!! This is terrible!!!!!! now my fault is reported again let's see if someone makes it this time!!!
