Complaint Review: Why Not Lease It

 I applied for a kmart credit card and a reciept came out saying to call a number in ten days to find out why i wasn't immediately approved. Another reciept came out saying i was preapproved for a lease of $1000 with why not lease it cashier gave me information on what I could purchase with it so i went shopping for an hour and a half looking for things to buy with the lease. Afterward i went to checkout and the cashier entered the code on the preapproved receipt and i was then told i was no longer approved and the lease was denied. How can i be preapproved but after an hour and a half of shopping be then told i was not approved. Cashier called why not lease it customer service and the man said it was denied but that I could reapply in 31 days. Um no thanks! Im not wasting any more of my time! Kmart has now lost a customer !
