I will say one thing about this - Swagbucks seems to make it right at the end, even when my record keeping is faulty. I just got paid for a survey or product test I did back in June (3 months ago!) I hadn’t taken a screenshot even though it was a sizeable amount of SB for the survey. I don’t even remember what the survey was because it had been so long.
Sure it took a long time and probably well past the time they said they’d award my account, but it eventually hit my account. Lately, I’ve tried to take screenshots after I do a survey of decent value that pays x number of days or weeks later, but I’m finding that I probably don’t need to. Plus I don’t want to write a ticket for a survey that didn’t pay on time, only to get credited by customer service and then double credited later. Plus some of the surveys have disqualification messages in the activity, but I did complete them and I’m pretty sure I’ve gotten credited as agreed for most of them.
