Why is wrong with bitdefender? My sub was also expired early this year and I bought two code from shoppe seller. It was 5 devices 2 year and 3 year codes bitdefender total security and yes the code can be stacked with max of five years

Later use that code to merge/extend my sub. My current subs merge fine with expire date till 2028

Then, I chat with bitdefender cs to change my plan from 5 devices to 10 devices limit by deducting 3 months from my subscription duration

If extend using cc for renewal, the price is way expensive, so just find authorize/legit seller from shoppe to buy the code
