How do you know they did delete the data? Do you honestly believe they are sorry and they deleted your data just because they said so? I personally doubt it.

How do you know they did delete the data? Do you honestly believe they are sorry and they deleted your data just because they said so? I personally doubt it. It's valuable for the company and it would be foolish (from their perspective) to delete it. Somebody has to write & test code, to make sure that the code uploads all your contacts. I find it hard to believe that you have access to all the data, see what is coming in, and then discover, when you're caught that "ups, we did a mistake". Our implementation sucked.
