Very poor service from Home connect

I moved home at the end of December and I contacted home connect at the beginning of December asking them to assist me with moving my fibre line to the new address at the end of December. All the relevant documents were completed and I was informed that everything was in order. When I came to the end December nothing was done and I had to start the entire process again. I spent hours with several different people on the phone. The internet was connected only in the first week of January. My account was paid every month although they gave me.poor service. I am recieving phone emails and messages every day stating that my account is outstanding although I made payment every month. I also sent through proof of payments.to several people but they keep suspending my account and I have to call them every day to re instate the service as my account has been paid . They even tried taking money of my account via debit order which bounced and I had to pay the penalty. I have sent several messages and emails for a.senior manager to call me but this never happened. Home connect service is really petectic and I need this account resolved ASAP.
