Texting with Alcatel 3XL

May 6, 2018
Why do my text messages from my Bank come with the heading from Tesco Mobile? I see a message from Tesco Mobile ... open it and it's actually a message from someone else. Eg My Dentist or Bank or Littlewoods. Why aren't my Littlewoods texts being notified to me with Littlewoods? Please help if you can.
