DotActiv runs initial checks to ensure the data is in the correct format. However, it is not DotActiv's responsibility to ensure the data is correct.
If DotActiv finds an issue, it works with your IT team to solve it. A solution includes clearing out your data so that you can re-script it.
If DotActiv finds that the error is because of your negligence, DotActiv can bill for this time at its discretion.
