Is it possible to call into Maxis to check for 14 pro max stock availability?

Went to a few maxis dealers to enquire regarding contract extension with my 128 plan, was told that whatever plan I’m on now, need to add one subline before they will sell me any iPhone 14, and to make matter worse, my 2 sublines are currently occupied, and I need to upgrade my plan to 158 so that the new sup-line can be added. How ridiculous was that?!. I decided to go maxis center in gardens and the incharge personnel told me that the allocation for walk in has all taken up for the day but they have stock if I add on one sup-line. Maxis is full of crap now!

Went to maxis the gardens, not just they tell me to subscribe to a new share line, I also have to pay an amount of upfront, even though I am asking for zerolution. This is ridiculous.
Two years ago I got iPhone 12 pro online from their website, without the need for any upfront.
