Wi-fi Router Repairs and Confirguration

On the 7th of February 2016, we called 10210 regarding the faulty router.The telephone consultant gave us instructions which we followed but unfortunately the router was still flashing and couldn't connect. We explained to the lady and she gave us a reference number which I'll get today at the shop. Now, the guys at the shop called again on the 9th/10th and the Technician came on the 11th February. He asked for the routers login details but the guys at the shop didn't have it so his return on the 12th was now to fix the probelm. He fixed the router but then said to configure we would have to pay him extra which to me is ridiculous. I spoke to him and he said his job was to come fix the problem and not configure the wi-fi. If the wi-fi didn't have any problems we would not have to configure and subsequently pay any configuration fees. I went to The Glen yesterday(20-Feb-2016) a lady told me that I will have to bring the router to the shop and the laptop for configuration. That really made me upset, whose petrol must I use and time? Wi-fi is an added benefit to our clients and we use it for our social media marketing this is really an inconvenience to out business (Hair Salon).
