ONE MONTH and DSL is still not activated

Hello,

So here is my journey to get a simple internet connexion ...

13.06     I booked the O2 DSL online

17.06     I received the contract and got an technician appointment on 06.07

06.07     The technician never show up. I still received an email saying that my DSL connection was activated. A few hours later I called the Hotline, she said that I will be contacted by them the day after.

07.07     I got an SMS telling me to call the hotline. I did, could get any one for more than one hour.

08.07     Same thing I gave up after one hour.

10.07     Same again.

TODAY    I don't know what to do ?

Help is more than needed here ☺️. 

How to deal with that ?

Thanks
