MilPark Education Bad Service

I have completed my application for PG Diploma (Accounting) and got admission and they sent me a registration form for me to complete and sent it back with a Proof of Payment , i paid the whole fees in advance and sent the POP with the registration form as requested till today they have not given me a feedback with regard to my registration , when i try to access my profile on their online system it says am not yet registered ...its been a week following up with them everyday and they keep telling me that they are busy processing my registration ....I Totally regret trying to register in that institution even worse paying all the fees for the course in advance , their service is bad
