Customer retention is easy, just be willing to assist

Not really a complain but, I think it's unprofessional to put a customer on hold, due to your own technical difficulties and then hang up whilst the customer is holding, and have no decency to call back the customer

Mine was a simple query, "Please test my unit" , I'm more than happy to take my business elsewhere if my little R220 is not enough to get proper customer service, @Gerome, or something along those lines couldn't get your name properly.
