Target group: those who appreciate quality

At Diners Club we value your opinions. Thus, a complaint may be placed by each client, either individual or corporate, either using the DC card, only applying for one, or just a recipient of our marketing offer. You may complain about anything that raises your objections as far as our service or performed activities are concerned. Each case is thoroughly investigated, so that any inconvenience gets eliminated and service quality improved. Our main objective is to ensure our Clients’ full satisfaction from using Diners Club cards.
