Poor Service

I purchased a PS5 initially when takealot gave the voucher to get it at 7999 and then when we processed payment it's said error. Then takealot sent another message of a voucher drop at 2 and I purchased it for 9999 this was Monday, Tuesday we received an email to send through a copy of my id and card number within 72 hours, we sent it within 5 minutes and today not even 72 hours later I get an email that the order is cancelled, my kids were so excited and now I have to go back to them and let them down because of takealots poor service no phone call nothing just cancelled my order
