Start complaining. That's the advice some experts are giving consumers, who across a variety of industries are suffering from bad service. A quarter of banking customers in the GCC, for instance, plan to switch financial institutions by the end of the year. One of the primary factors? Poor customer service.

In other countries, such as the US, some businesses have already set up Twitter accounts with teams solely dedicated to addressing complaints from customers.
