Messed up my credit profile

Please remove incorrect information on my profile. To my surprise when looking to apply for vehicle finance, i can declined due to Transunion having information on my profile that is incorrect. Clearscore whom i have check my profile with has none of the incorrect data that Transunion have yet the creditors believe what they say about your credit and they advise then when you send them an email tp update your information that they wil lget back to you in something like 2 weeks! No you messed up my profile you fix in immediately not in your own time! I am so furious
