Money hungry inconsistent unhelpful!

First off, I’ve been banking with FNB for incredibly long. Since my time with them, I’ve taken a few FNB deals along the way and always paid it up without skipping a payment. So obviously as my son’s birthday is coming on, I’d like to buy him a Playstation 4, and want it done through FNB. I submit the application and according to the affordability page, I’ve got a lot more monthly spend available than required but to my surprise, I’m declined, but allowed to check what I can get approval for. They’ve decline me for the R349 PS4 deal but approve me for a R849 sim only deal. Now they’d rather have me buy into the useless sim only that I have no use for, seeing as I’ve already got sim cards from them, but not an actual product I can use? And then spin me a story about affordability on one thing but not the other? That is incredibly pathetic from FNB and making me want to quit banking with them all together. The one consultant keeps on making up the one story after the other and when excalated, they tell me they don’t want to communicate telepathically anymore it will only be via emails so that I can’t ask my questions. Pathetic FNB!
