We thank Mr Mohan Varadarajalu for his feedback (Firms bypassing data protection rules?; Nov 18) and have contacted him to address his concerns.

The text messages sent to him previously were of a service-related nature.

Handling customer data responsibly is important to us, and we have in place a set of stringent policies and practices to protect customers' confidentiality and personal data.

This includes having robust systems and processes to ensure that customers do not receive marketing-related calls or text messages if they are registered with the national Do Not Call Registry, or had previously opted out of receiving marketing materials from DBS Bank.
