I have been using Quickheal Antivirus since long. earlier I have renewed it through Amazon & received GST Invoice too. This time I have directly renewed it form the link send by quickheal on 10th April 2023 & they have send with Invoice without GST No. After that I have called their No. as well as send emails many times but they keep on sending the same Invoice without GST No. Its advisable not to deal with the company directly as they are not concerned about the Client
