I am hotlink user which also comes with free spotify premium
but didn't receive any sms regarding about it

Maxis already had enough of customers. Our value in their management view is zero. Now the management want to test in how many people will port out when they removed the free Spotify Premium. Second stage will be reduce the internet quota. Maxis feels that they had offered too much during the previous crisis. As long as people are porting out but Maxis can maintain their profit, it is fine with them. They don't need to employ so many CS to take care of the huge customers thus saving operating cost. Maxis only want customer who is willing to accept what they offered, keep paying like water fish and no complaints.
