Poor service delivery

I have requested that my internet line be moved to my new address in November 2018 and we are almost in February 2019 !!!! They have given me the run around now for way too long always someone else at fault!! Ive been to the shops numerous times and i have phoned the customer service numerous times and well I’m fed up!! How hard can this be?? Absolutely poor service!! I need escalation on this matter!!
