Being convinced of the way of service. This is where Convins came into being. The name "Convins" is derived from "Convince," the idea being that a telemarketing agency must be convinced of its commercial qualities in order to take on projects. We are now over 14 years and sixty colleagues down the road. The transparent communication and complete clarity has always remained. Not only to the customer, but also internally. Literally. In our offices, the rooms have glass doors and windows. So you always know who is working for you.
