Online order

What a horrible experience buying laptop online at game😡when I was done paying I was informed that my order has not been successful even though money came out of my bank.I called customer help line and spoken with a gentleman called Katleko who was super nice and advised me that it may happen that the items is no longer available online and he said he will help me get my refund which can only reflect in 14 days that time this item I bought it for my child and it’s needed this weekend as he is leaving Cape Town. He said he will get me an item from Promenade mall and I should receive an email confirmation for collection date. Supper annoyed why would you advertise something that is not available and take payment of it then give me oops it’s not available anymore.
