Status of maintenance/Internet Issues since October 21st

I'm experiencing some internet issues that suddenly started on October 21st around 1:00 p.m. I contacted KPN support several times, and we scheduled a technician appointment. (the problem is that my internet is very bad now)

The technician visited our house, checked the situation, and determined that the issue isn't with our devices nor with the KPN modem in our house, he said that it's likely that the problem lies somewhere in the optic fiber cable. He mentioned that KPN will monitor my internet for 2 days and then will reach out to the cable company about the issue. 

I don't know where to ask about the status of this situation.

p.s. I hope it's alright to communicate in English here.
