Upgrad — Upgrad not refunding my money and denying to cancel my application.
Before applying they were claiming they don't need any ILETS and now asking for ILETS.
They are scamming peoples.
I applied MBA in IU University of applied sciences, Germany through upgrad's study abroad program.
I had done all the formalities, and they told to submit all the money at once or take a loan. I couldn't pay the total money so I took a loan of 2.5 lakhs through zest money which was suggested by upgrad.
They were in a hurry and did all the procesdures and then afterwards when I had problems they seldom picked up the calls. Later I decided to withdraw my application and so i contacted them, i was unaware of the policies and even the officials didn't tell me anything about it. They did all the process by taking me in a zoom call and they guided me what to do next. I had paid a total of 25 thousand to lock seat deposit and 2.5 lakhs loan Is ongoing through zest money. I contacted the upgrad finance team before the start date, they didn't help and told me to contact the counsellor who didn't pickup the call because she wasn't available and the later she replied to me She had left the company .
Later when I contacted them they told that they can't refund because the start date is over, and they said loan can't be cancelled and i have to pay full money even if i cancel the application.
I contacted the university for the same, and they said refund is given from the university side but i[censored]pgrad tells them they will give they refund and cancel the application.But upgrad is not ready to help nor support, they are asking me to continue the course .
Please help me sir/ma'am.I am in a big trouble and Upgrad is scamming like this. And Asking to pay the full money.
