Several issues with KPN internet

Hello,

I 've recently bought internet from KPN, from the beginning I had several problems because I couldn ' t log in and make an appointment with a technician to connect my internet. After raising the issue here in forum someone made an appointment for me. A technician came and installed the wifi. But afterwards I wasn ' t printable to connect to the internet using my devices (including mobile, laptop etc). Now I wanted to add  “internet ” as a product to my  profile and it 's saying “ You are not connected to your KPN internet connection. ”! How can this be possible?
Please ask a tech nician to come and fix my internet after this long time and please fix my profile.
