TFG "Mr Clinton Wood"

I have been trying to but something online for the past 2 days, yesterday the item sold out, because I was stuck at the place my order button for about a hour, today the same thing happened sneaker was released and I was on the site at 8:50 selected everything and confirmed everything and I was stuck at the place my order button, I had 5 people trying from different devices for the specific item.

No success, my dad then received a email saying the order was placed, he went through the same procces as myself, but "Apparently he selected the wrong thing but my dad is a frequent online buyer so he knows exactly what he selects and they" Team Leader" at the call sent name "Clinton Wood" told me otherwise, and stated I have to pay via debit or credit card.

I have a egift voucher and it won't allow me to via this method.

Customer services from Mr Clinton Wood was 2/10 not helpful in finding a solution, he wanted me to pay via debit or credit card, I mean I have a TFG acc and a Egift for TFG and they won't assist me any how??

What's the purpose of a egift card option on the website if it never works?? And then Mr "Clinton Wood" insisted there is no way to help me but I mean they expect me to pay my acc every month but they can't offer a customer the best possible service
