Aftersales service?

Call logged on the 14th of March - Technician only responded late on the 17th of March after multiple calls from me as no one phoned me back from Bronbergwisp. Technician who was very unexperienced spent most of his time on the phone with a colleague who decided that the damage was caused by a surge - don't see how this is possible over the phone. There was no damage or burnt components on the router. I had no damage on any other equipment as I have a 2 stage surge protection installed on my DB board that supplies all appliances in my house. Then I was charged for this repair as they do not cover acts of God. Now less than a month later I have issues again with my connection being dropped all the time... I have also had issues to connect devices to the wifi router since their repair and have to sometimes restart the router to connect a device and some taking almost an hour of trying to get it connected. Just because of the fact that I will probably get the same levels of service now I reverted back to my 3g router and got all my devices connected in less than 5 minutes.... I have also not received a report back that I have requested on the failure of the router which gives me the impression that they don't care about their customers and just want to make money no matter what!
