As soon as money was in their pocket ,customer service was gone

Order a few cakes from quality bake express in diep river via email on teusday. Communication back and forth via email was good, Even when i collected my order the lady was nice.. but to my suprise when the cake got cut which was suppose to be a 4 layer chocolate mousse cake as per order turned out to be a bar one cake so i was stuck with a 4 and 2 layer bar one cake any way the party went on with the wrong cake was not gonna spoil the birthday.. thursday morning i emailed the bakery with pictures attached telling them my order was incorrect.. to date i still did not get any explanation or apology these same people that emailed after 5pm on teusday that now already has the money does not reply ..As a south African i always support south african companies but with this aftersales service i wont even refer people to them... they probabaly thought i wont know the difference because its my first time ordering from them not knowing,I order normally from The same bakery in landsdown and i normally order the same cakes.. so i know this was no chocolate mousse cake...not once in my email did i request a refund all i did was to tell them the order was wrong and it was very dissapointing.. An explanation would have suffice..
