The "collection mail" clearly states that your travel document and supporting documents (if any) are ready to be picked up at the TLScontact Application Center in Accra.
You can pick them up, or you can send another person to do so; the letter describes what documents must be shown by the person making the pickup.
The letter does not state if your application was successful or if it was denied. While this form letter does not specify the result of your application, form letters like this are often used in the visa application process to advise the applicant that the application has now been processed.
This website is not TLSContact; no one here knows whether your application was successful or not. You will find out when your travel document (and other documents, if any) are physically handed to you or to your representative at the contact center in Accra.
