I own my own stump grinding business and just recently bought out another company. The other company had a customer that was very unsatisfied with the work they had done so i as the new owner went back to the property and reground the stump they had the claim about and ground 2 more small ones as a courtesy thing for the sloppy job they had done which i agree was the worst grind job id ever seen. Now the customer keeps calling saying they wont be happy and will give me bad remarks in the community if i dont go grind out 2 more stumps for them for free. I have already stated to them that i have ground 2 additional stumps plus reground the stump they had complained about to begin with out of my pocket and explained to them i purchased the other company and i was the new owner. WHAT DO I DO? Would you let them black mail you to make a happy customer or just say screw it and take the negative and pretty much tell them to screw off. I would hate to lose a customer that wasnt even mine originally but dont want to be taken advantage of either. What Do I Do?
