Stuck on building a customer support chatbot from scratch using reddit dataset
Welcome to the site! I'm going to make some assumptions here to clarify your question and attempt to give you some guidance: it sounds like (1) you are working with a general chatbot framework and (2) that framework has been trained on a dataset that contains text from reddit. 

So, what you need to do is now take that framework and train it again on your own custom dataset (relating to colleges?). I'm assuming that the training can be done based on using a chatbot framework that has this flexibility. 

At this point it would beneficial if you posted (1) which chatbot framework you are using and (2) tell us about your data. Do you have a lot of it? Is it in question and answer format?
