As so many people do, you are mixing up two different terms.
The seven-year credit report time period for negative information does not start over. Never.
What may start over is the time period in which you may be sued. In other words, whenever you do something regarding your debt – the statute of limitations clock is reset.
So basically, even if the collection agency would report the payment(s), they should not appear on your credit report and should not affect your credit score in any way whatsoever.
Having said that, it’s always a good practice to take extra caution, especially when dealing with debt collectors. So before you contact the collection agency make sure you know how to deal with them.
Hope this helps.
