I did a application online and after i finish  and i summit my application i got approved and payed only for the  cell phones,  2 mins later  i called them  if  everything was  fine  and they told me  they have to cancel the order because i was not  approve  but  they told me  this after they  charge my account $220 dollars and  i told them   where is my money they told me  that i have to wait  7  to  10  business  days  to get my money back  this  is really ridiculous  how are they going to take my money and then  say no now i am stuck  with no phone and no money to buy me a new phone.
