Vodafone has announced its pay as you go customers will be rewarded for their loyalty with a new scheme called Vodafone "Bonus Bank".
Every time a customer tops up, Vodafone promises to "give 10% back". For example, for every £10 top up, the mobile operator will add £1 to the customer's Vodafone Bonus Bank account "to save and spend at a later date".
Then, after 3 months - and - as long as the customer has racked up a minimum of £5, the customer can then spend their Vodafone Bonus Bank savings on credit, or towards a new handset.
This scheme is not automatic. If you want to register you need to text "BonusBank" to 2345 or call 2345 from your Vodafone handset.
