Hi @Alexa.kv and welcome to our forum! I can imagine it's frustrating if you have to wait for your services longer than initially communicated. I'm sorry to read this made working from home difficult as well. I can't refund the €25,- connection costs however. These are charged for connecting you to our network, our services and our system. You’ve been connected to all these, albeit later than you wanted. They are also stated in your contract and will therefore be charged. In the initial confirmation e-mail the following was communicated:

“U hebt ons gevraagd om uw abonnement te starten op 15 juni 2022. Wij controleren nu of dit mogelijk is. U ontvangt nog een aparte e-mail van ons met extra informatie over uw bestelling. Hierin staat ook de definitieve startdatum van uw abonnement.”

This means that the date you entered as your preferred date isn't set in stone yet and is likely to change still. That's what happened here, so unfortunately I cannot refund the connection costs. 

Regarding your fibre cable, I see you were transferred to the KPN Netwerk (the fibre company) when you called on the 5th of July. I'm sorry to read the lines were busy. There are different ways of reaching them, so if calling isn't working out you can try one of the other options at the bottom of their contact page. I hope you'll have more luck with getting in touch with them then. There's little else I can do but what I stated in this message, but if you’re running into any other difficulties or need clarity on some things, do let me know! I'd be happy to check what I can find out and I hope you'll get more clarity on the fibre connection soon.
