I think at some point you say enough is enough and throw the credit in the thrash no matter where you get it from. How long would you give someone a chance with any poor product. Whether it be coral, cars, construction companies, service companies...etc. It does not matter the situation. Sometimes enough is enough. If it is a few corals, in this case, then sometimes bad things happen. If it is ALL corals in a shipment, then I would say enough is enough and take my business elsewhere.
Each scenerio is different. MOST brick and mortars do NOT offer guarantees.
