AUDON Excellent Service
29 January 2021  |  Michael

I have been exceptionaly pleased with the service from AUDON. I needed some help for a few issues. Some in which I asked for pre-sales technical help. One in which I made a mistake. Another soemthing I bought a year ago went faulty and they arranged a simple exchange. They have been so good to me, they have been a breath of fresh air in the world of "customer service". Thanks, Mike
