When NIIT Noida was under Kando Enterprises and His head was Rachna Mam. I had completed my 80% course. I had an emergency at home. Then I gone my home. After going home, I came to know from my colleagues that the Noida Centre will be closing soon. Then I contacted Rachna mam and she said transfer your course. I said ok and after a few days I came back from home, the center was closed, I asked Rachna Mam she said just go to NIIT CP and contact him I went there he was also said that contact to the headquarter office. Then When I contacted my colleague, he said that brother, we got refund my fee amount. Then there was an emergency in my house and I went the village and at the time of arrival, Lockdown was started.
