@Ruandsu Hey there, thanks for getting in touch!
I'm sorry to hear about this. If you send a private message, we'll check to see if there is anything preventing you from using the card online.
If there are no blocks or restrictions, it could be a problem with 3D secure which is the system used to verify the card for online purchases. If this is the case, you'll need to call us to resolve this.
If you need to ask a question about a Tesco Bank product, you can make a post in Help & Support here
