Who was the most challenging customer -- internal or external -- and how did you satisfy that person?

Since Currently I am providing Technical Support to Consumer Customers for Etisalat, I feel that Customers who are External are most challenging to deal with.. and are difficult to handle many at times.Once you had resolved the Customers Issues then they easily become manageable.

the irrigated customer; they always unhappy and use loud voice

usually they have a valid point and know how to attack

being expert of what you are doing is the first step to satisfy them

being calm and showing understanding

Active listening and empathy 

The client is the most deviate internal customer because he has experience with what is related services and assistance

For I did for me as a gateway service that is dealt with, such as dealing with the external customer accordance with the regulations

Internal customer is the most difficult customer to satisfy because these are directly influenced by the organization procedure, policies and culture & if we satisfy the internal customer, we can get highest rank of satisfaction from the external customer.

We can satisfy internal customer through maintaining standards, strong HR department, understandable & easy procedures, mature policies, through promoting positive culture in an organization and with good rewards e.g: Dulux, Nestle.
