1. I bought an acrobat pro 2020 retail serial number from www.adobe.com official website,Order number: AB03416407545CUS, 2. This is a legitimate serial number that I paid a lot of money to buy. 3. I was testing how many accounts I could activate, but you blocked this serial number. 4. The reason your company gave me was that the maximum number of activations had been exceeded, so the serial number was blocked. 5. The protocol description I saw on your official website is that you can activate up to two computers, one of which is online at the same time, but it does not say that the serial number will be blocked if the maximum number of activated computers is exceeded. 6. You should use technical restrictions to activate the computer instead of blocking the serial number. Blocking the serial number is not something a large company with technology does to harm consumers. 7. I have been in contact with your after-sales service for more than 15 days, but they have always said that this private agreement that is not expressly stated on the Internet is the final result. The private agreement is not legal and I cannot accept this private agreement. 8. No one has been able to solve my problem of wrongful killing of serial numbers. I can only ask who to provide me with justice.
