Prestashop 1.6 - Show Customer Group in Account page (Front End)

I created 5 customer groups in back-end for my customers. I assigned a customer group for each of them based on orders. I would like to show customer groups in front-end for every customer in his account details page. Best would be to create a new tab in account details page and when he click there he can see in what group he is and stars and some text about group system. max budget is $20 Type: PRESTA otherwise I will ignore the bid. See attached screenshot. There should Cateogory TAB and when somebody click on it should be info how many stars he's got.
