How to change email address?.
That’s frustrating. Getting bounced around when there’s an unauthorized charge is the worst. Sometimes account issues get mixed up with device-level problems too, especially when systems are already under load or behaving oddly. When I get into something similar, I found it helpful to first rule out general system performance bottlenecks before going back and forth with support. (It can be easily checked by any bottleneck calculator like this one.)
Hope AVG support resolves this quickly for you!
