I was using a utility supplier for 18 months. Every month, paid my direct debit on time. One day, they reviewed my account and said they had miscalculated my energy consumption and I now owe them £900.
I switched energy suppliers straight away as a consequence.
I am now being contacted by UK Search Limited by phone, email and text message. So far, I haven't responded and don't intend to.
I've checked my credit file. The account with the original utility supplier is closed and settled according to Credit Karma.
So what should I do with UK Search Limited? As far as I see it:
Completely ignore them until they go away (my preferred option)
Contact them in some way and dispute the debt
I would be very grateful for any advice on how to proceed. I currently have an excellent credit score.
