Pip review complete

Hi I am trying to help my mum with her claim

She has received the following text “Your PIP review is complete. You should receive your decision letter in 2 weeks. Once you receive your letter, contact us if you have any questions. Do not call before you get the letter as we will not be able to tell you the decision. Please remember to contact us if your circumstances change.”

Is there anyway to find out early for her?
