The **** service

I just want to say that the first individual that assisted me on the sale was great. I am just a bit confused, the sales lady did all my checks and read me the T/C and advised me that I do qualify they just don't have stock of the devise. I advised her that it is OK I'll wait. So how is it possible that I get an SMS now stating that "during credit vetting" they have declined it....... but upfront the sales lady stated i qualify. So i think they cant get the devise in stock and now they use the decline as an excuse.... I have a great credit score, so I do not know what they are talking about....
