Poor customer service from Singtel

I sent this e-mail to Singtel 8 days ago. I did not receive any reply or acknowledgement or even a telephone call. This is  a deplorable standard of customer service that is typical of most big organizations in Singapore. These are organisations that pride themselves on excellence. What excellence, when they refused to give a reply to a customer?

According to CNA, Singtel wants to build a cloud computing business. Perhaps they should start by replying to e-mails promptly.
