Our bath held hostage

We asked for recommendations for someone to help us restore our cast iron bath we found in a s****yard and the Mend A Bath gentleman from Gonubie came highly recommended. We duly engaged his services and he collected our tub. When he returned it my husband was not happy that the external quality of the bath did not match the internal, a disagreement ensued and finally he agreed to collect the bath again and make good. When he arrived at our home his anger was directed at me and I could see he was moments away from losing his temper, but remained civil. I suggested his concerns be directed at my husband as he was the one not happy with the workmanship. When our tub was finally ready to be returned, the Mend A Bath Franchisee demanded payment in full BEFORE he would return our bath. We duly noted that the terms on the invoice are C.O.D. The day of delivery he dropped the bath while loading it, but only contacted me to inform me at the stipulated time of delivery, thus fuelling my concern that our tub would not be returned. She was eventually returned and on the day the gentleman in question was again extremely rude. For a franchisee I find this behaviour very distasteful and I will not recommend this gentleman going forward.
