BYOD Problem

We are new customers that purchased one phone and after being told our 2 current devices are compatible for use with cricket were planning on bringing our own devices for 2 other lines. We received our sim cards however they won't make or receive calls and after many hours on the phone with technical support have been told they are actually not compatible with the cricket network and we will have to purchase new phones for these 2 lines. However since the numbers have already been ported from our previous company they are considering us current customers and won't let us purchase phones with the new customer pricing, even though we haven't even ever had functional service with them. I feel like the new customer pricing should be honored since we were told our phones would work and that's why we didn't purchase additional new phones with our original order. I know we will be paying higher prices in the future which I get. But to charge us higher rates as a current customer when our service hasn't even been working when we were told it would is very frustrating. It has been a very disappointing switch over to this company.
