Hi,

I called U-Mobile and managed to speak with their customer service officer. I want to unsubscribe from their marketing/promotion materials since they keep spamming SMS every single day for 2-3 times a day.

But the officer said they unable to proceed with my request since it's a must for U-mobile cust to receive the sms.

Is this true?

This is the first time as a customer of using any service I've been forced to accept their marketing materials
