Deactivated Account

We are Soft H2O and have no association with any other company. Thumbtack claims we are tied to an irrigation company but can not give me any details. We have been with them for8 years and they randomly just deactivated our account interrupting our business tremendously. I can’t get answers from anyone! I’m sadden by the sudden deactivation and the claims it was a through investigation. If it was through we would not be here because we are not associated with any other company. Really really upsetting. Anyone have insight On this?
