Bad and poor customer service

I have my WiFi with Home Connect. I have always been happy with their service until recently. I recently moved to my new house. Couple weeks before I moved, I called Home Connect regarding connectivity issues. While on the call I asked the lady consultant I was talking to the process as I’m buying a new house. She said I must call before I move. That is exactly what I did. I was so shocked when I was told by the consultant I spoke with that I was supposed to have given a 30day notice for the connectivity of my old house to be cancelled. I explained to her that I did call and the consultant I spoke with at the time did not say that. She said she will speak to her supervisor to listen to the recordings and will definitely come back to me. After couple of days when no one came back to me I called back twice after promised the same thing that someone will call back. The last call I did was on 23rd September. Fortunately I spoke to the same consultant who promised that the supervisor will call back and explained that someone will call but no one did. Still nothing on the 24th even though I was promised that someone was going to come back to me the same day. I sent an email in the 24th and no one bothered to respond to it, I only received the automated receipt email. I explain to the lady my unhappiness with having to pay 2 WiFi connections for October for 2 houses whereas I only stay in one and on top of it I was misinformed by a Home Connect consultant. I received a bill and they deducted the money for the 2 houses. I am annoyed and furious with this as it is *******. At least someone should have called me back as promised and listened to the recordings and not for them to keep quite and just deduct as they wish. This time around their customer service was very poor.
