Invoice Issue - No Internet Connection service

[SL2B]

I was subscripted to the cable service for my new flat back at the beginning of August.  It has been almost 3 months and I still do not have any Internet connection yet.  Currently, I am still in a process of requesting to set up an appointment with the technician.   In the meantime,  I have been paying Vodafone for the past couple of months,  I would like to ask for credit on the months that I have no services.  Please help me to solve this matter.  Thanks!
