Ways to maintain customer trust

What are some indicators that shows customers are considering alternative to your product / service. Can we overcome those.

1.Perhaps just a curious try to sample  other options  – On the surface of it the company may not recognize that customers are trying options. In fact customers could have been very happy with the company, but company needs to think and asses what are market offerings / new entry in their product domains. This might at least provide an opportunity to the company if they need to consider new ideas that are coming into their segments but not offered by them.

2.Customers sense their vendor is not showing consistent commitment and service levels are down – Need to analyze and ensure short-term and long-term trust is reestablished. Still it is possible to get back customer into trusting the company

3.Dissatisfied customers – Frequent service level failures will lead to customer choosing competitors. Almost impossible to get back  unless a breakthrough innovation in product quality, service level and commitment are delivered.
