They are awful to deal with.
DH signed us up with them, and he gave the notice at the end when we wanted to leave.
He then went away for three months with work, while I stayed at home and had Virgin Media call the landline two or three times a day, every day, asking for DH.
They would not accept that he was away and would not be home for weeks.
They would not speak to me, as DH was the name on the contract, and "Data Protection Act" meant I wasn't allowed to know what they were ringing for.
I said I knew what they were ringing for, he'd ended the contract and they wanted him to continue with it.
They denied it.
When I said he had given permission for me to speak to them they asked me for a password. When I gave it to them, they lied and said that was the wrong one.
When I confirmed it with DH, during one of our limited calls together, he confirmed it was the right one.
When I gave them it again, they lied again.
They refused to stop calling. They said that I could not tell them to stop calling for DH because they owned the landline so they could call it if they wanted, and he was their customer so he had to tell them to stop calling him.
I kept asking them what the point was, in ringing me two or three times a day just to tell me they weren't going to speak to me.
Eventually one really rude woman said that if DH was really working away, she would ring his mobile phone and speak to him.
I told her good luck with that, as he was working in a bloody war zone and even I wasn't able to ring him when I wanted to.
She said she'd do it anyway, and read out his mobile number to prove it to me.
It turns out they had his old mobile number, so I told her he had a new one.
She asked me what his new number was. I said "Data protection act says I can't tell you that" and she put the phone down on me.
It took complaining publicly on Facebook to get the daily calls to stop. They are aggressive salespeople who don't give one tiny shit about their customers or the stress they cause to people. They want money and once they have it they don't care how they keep it.
