Request to remove comment of phone number

Just had a telephone call from this number- lady asking me to confirm my address and saying I had overpaid on loan repayments as PPI had been added without me asking for it. Asked me to confirm my address - they had an old one listed. I told them it was incorrect and asked me to give them my new one. I asked her to confirm where she was calling from first - she said Halifax Reactive. I said I have never borrow money or indeed banked with Halifax, and she got very rude and said 'I never said I was calling from the Halifax, our company is just based there'. Stroppy moose. I asked her what company she thought owed me money while I had lived at the address they had listed, knowing that I had taken out no loans, credit, finance etc whilst living there. She said she didn't have that info and needed my current address. I refused to give it to her, and she got pretty rude - when I told her I thought she was being aggressive considering she was cold calling me, she got worse and said it was not a cold call! Very peculiar and I will be reporting this. Incidentally, when I Googled Reactive Halifax it came up as a pest control service.... Almost want them to call again so that I can ask her more about where she is calling from while she is on the line..
