buying problems

i want to buy vape client using Venmo but currently do not have a way to connect a bank, i have a Venmo balance but no connected credit cards, debit cards, or bank. and i cannot connect those. i have a balance of 25 dollars which is enough for the summer sale. can someone please tell me if there...

Today I tried to buy vape v4 with my credit card then it said: Error! Please check your data and try again!. But I put all correct things and checked multiple times please help.
