Customer Services

Sigma provide a range of customer service contact solutions - all delivering a great customer experience

Sigma's advisers go through an in depth training programme where providing an excellent customer outcome is instilled in them from day one.  No matter what the service, they will endeavour to gain complete customer satisfaction.

Flexible customer service/credit management hybrid services are offered alongside the more traditional customer service offerings:


The successful and speedy resolution of customer queries and disputes can not only prevent queries escalating into complaints, but can also boost sales and customer retention.

Sigma's highly skilled customer advisors are able to work query and dispute accounts with full access to clients’ systems.


Complaints are a great source of customer feedback and their successful handling is a unique skill-set. Sigma's advisors are experienced, skilled and able to handle customer complaints at source; reducing customer churn and helping to prevent any escalation.


Sigma is able to provide inbound and outbound new business sales calls solutions for clients.

Customer service calls also provide excellent opportunities to offer existing customers new and improved products or services.


Sigma's customer advisors are trained to connect with customers in order to handle initial objections and queries and retain their trust in our clients' brands.
