When two companies merge, what should you do? It’s become clear that you should head for the hills. Companies say they’re merging to benefit you, but it’s just a line. According to a recent study published in the Chicago Tribune, customers were unhappy 100 percent of the time when a company they did business with merged with another company. And that was two years after the merge happened. It’s not smart for the merging businesses either. Banks lose a quarter to a third of their customers when they merge. So, if you hear that a merger is about to happen, think about switching companies. There will be some hassle in the beginning but it will be worth it. You will experience nothing but customer-no-service after the merger.
