Apparently their support system goes ignored. I have used them for a long time but now i keep getting a message "Pending buy, once your verify your credit card information the order will complete", if i click more info it will say pending buy again. I deleted my card and tried to re-add it but I get the "pending buy" message in a box instead.. im stuck on this damn pending buy and they have absolutely no help for this
Regard to this issue, you have to wait for at least a day so as to be approved to buy again. Everything is in pending so it is apparent that you can't do anything to make it faster
Personally, I feel that blockchain can't not have a good service like other exchange or wallet providers such as Binance and Coinbase. Gemini is also a good option because it has a high secure app with lot of advance features
