Poor Service

I was referred by my University to LightBulb Learning, to help with Exams preparations, but the learning center is a nightmare. I paid for the package to help me prepare for the exam which is on the 09/11/2020. When I communicated with them before I paid, they were very quick to respond, but now after I have paid, they are nowhere to be found. The package they promised on their website is not what I am receiving. Their answers to the online Case Studies have lot of errors and there is one case study that does not have Facts. I have sent them numerous emails and messages, with no response. I should be studying right now but I am figuring out how I can resolve this. This is causing me so much stress that I don't need. This was supposed to help me prepare for my exams, but instead, it is adding to my stress. I even feel like, these people are trying to sabotage me. I want my money back.
