No internet and landline with newly installed fibre

<p>On the 16th of April I got fibre service installed. Since this time I have intermittent internet connection, mostly over the whole working day without internet and also an interferenced landline with disturbing noises. On the 18th of April I got a fault reference number 181CNK180417. On the 21th of April I got an SMS, that my fault has been restored. It was not! After several calls in your sevice center a new fault number 573CNK250417 was created. Since then the situation get worse than ever. No internet and landline the whole day and I had to buy expensive data from my cellphone provider. I called your service center again and asked for a port reset, but that didn't helped. I got an escalation reference number 978924. After 2 weeks of suffering I have to ask you to bring my ADSL line back or resgore my line urgently. </p>
