Ridiculous demands

App**** for a cellphone ontract and they told me that i would need to build my credit score because my credit life is short. I build it and app**** again and met all the criteria and then they comeback and say i dont qualify for a phone, just a sim... Tried again months later got approved but suddenly i dont qualify for a high end phone... so no I phones or samsungs.... wgich is absolutely ridiculous. Why would i downgrade from my current phone when ive never had history of not paying.... Goal post keeps moving with this store but im certainly dissapointed after working so hard to meet their criteria
