Resolving your complaints

All calls are recorded for training and quality assurance purposes. Our customer services agents have been trained to demonstrate an utmost level of professionalism and respect for our valued customers.

Our team will try their best to resolve your issues within five working days after receiving your complaint. However, for matters that require input from other departments, they may need to escalate the issue to the appropriate person or specialized team to handle.

We expect that such escalated issues will be resolved within 5 working days, depending on the nature of the complaint. However, there are some complaints that depend on our technical agents and such matters may take up to 30 calendar days to resolve.

Disputes may be resolved by an apology, explanation, corrective action and financial compensation in appropriate circumstances.

If you are unhappy with how we have handled your complaint, we will carry out an internal review and will let you know within 5 working days. We will tell you how long we expect it will take to resolve the issue.
