Cable internet still not activated

I have signed fro Cable Interned on 11.01. Therefore received a technician appointment on 17.01 and eventually I missed the phone call and the technician never came. 

On 26th, I called the English hotline to make another appointment, the guy redirected me to “activation team” but nobody ever picked up. I called 3 times. Thus, I could not make another technician appointment. 

My activation date is today (02.02). 

In the meantime I received the router and I plugged it into the socket. I connected to the network and was able to see the O2 homepage, which basically says that the connection is ready, and only needs to be activated. 

My question: Do I need another appointment for technician? Can my connection be activated? 

In O2 portal it’s still “processing”. 

Thank you in advance for your reply.
