One in seven adults who has made a recent small digital payment ended up being billed more than expected or found themselves bombarded with marketing messages, according to a watchdog.

The survey of 4000 people , by premium rate services regulator PhonepayPlus, found more than half (55%) of adults had made a payment of up to £10 in the last six months.

Some 15% of users said they had encountered problems, such as being billed for something within an app like extras in a game which they thought were free or unwittingly agreeing to receive advertising texts.
