Bitdefender scam

Bitdefender deactivated the license I purchased without my knowledge. However, the company did not send me any notification of the change in terms and termination.
I sent them an email asking for a refund. However, there is no answer from the support service.
It is obvious that Bitdefender is cheating and fraudulent.
I do NOT recommend this antivirus. There is a high probability that you may get the money sooner or later.
