Dont use Synergy Digital Marketing useless

Gordon from Synergy Digital Marketing oversold, could not deliver and cost me my companies sales for the 14 days they ran my google ads campaigns. Their campaigns had no results. He mad promises and sold the company as one that knew what they were doing but once I looked them up properly all I found was that they only have 1 qualified staff member in search campaigns only. When I confronted them they put the phone down on me. Refuse to refund me and now I am getting a legal to resolve the issues.
