TalkTalk is stopping advertising for the moment after the cyber attack on the firm.
The British company has said it wants to focus on supporting and reassuring customers.
Yesterday, it confirmed some personal details were taken by hackers on Wednesday, but not full credit card numbers and passwords.
Cyber security consultant Dr Jessica Barker has said TalkTalk won't be the last to be hacked.
“Most organisations, if not all organisations, are struggling with cyber security it is a very complicated and difficult subject to deal with and organisations need more support, individuals need more support, so they can do all they can to ensure their information is safe.”
