A genuine mistake in us or Carphone Warehouse not cancelling our contract with Vodafone in 2011 meant that we are still being charged for the service in 2019 - the amount in the direct debit was not picked up in our bank account ( I know - our fault ). They had taken £1,900 from us for a service we did not have. Called them and explained August 2019, expecting some kind of refund maybe. Not a hope, your fault we were told so charges stand. OK take it on the chin and cancel the contract in the same phone call. Cancelled direct debit also on same day. Two months later I receive a demand and service suspended letter and a bill for £42.12 i.e the 2 months payments since I had cancelled the contract. Spent over an hour online to customer services explain but to no avail … Vodafone " the communications company" had a record of my call but no notes made cancelling the contract they said and the amount was due, moreover I would continue to be charged until the arrears were paid and they would not cancel the contract until I paid ………………………. disgraceful conduct from a jobsworthy company with no flexibility. I have been in business for many years and would not treat any customer the way the did me.
