Home Shopping Network HSN Confirmed order of UHD TV $2299.00 on Flex pay w/ my $1,700 credit limit Internet

 I was authorized for $1,700.00 credit of a HSN CC. I purchased a Samsung 65 inch curved Ultra/4K HD TV on Flex pay for $2299.00. They accepted my first Flex pay payment and had a projected ship date of 08/04/15. Then 4 Days later without so much as a phone call they blocked my account and canceled the order saying I needed to call the 'Verification ' Department since they had not verified some other 'important' personal information. After they already approved me for the credit line & purchase with flex pay.
