Request for my certificate

In 2019 I enrolled for a 3 month learnership in plumbing which consisted of a stipend,lunch and a certificate upon completion, according to the College they've been having a problem with the stipend being allocated to students as per contract,we only received PPE ,had to borrow money for transportation to attend our classes and had to bring our own lunch since we never received any ,I will like to atleast get my certificate because after enquiries about the certificate towards the end of the course we were told that they are there but they need to be signed by the College board,till today I haven't received my certificate and never got any feedback from the College
