Disappointing service delivery after payment

On the 13/05/15 I ordered and paid for a birthday carrot cake . The manager on duty accepted and asked me to write down the message to be written on the cake on a piece of paper, which I did. He then asked me to rewrite this in the stores diary, which i repeated. He said all was fine I paid and he asked when would i be collecting the cake i told him on the 18/03/15 at 10h00 he said lets rather make it for 14h00 on the said date. I agreed and left happily expecting to receive the delicious cake ordered for my fathers birthday. <br> <br> On the 18/03/15 in the morning i called the store to advise that i would not be collecting the cake myself and that my sister would and she does not have the invoice the manager on duty said that was fine . When my sister arrived to collect the cake .. there was no cake!!! I called teh store and expressed to the manager that I was unhappy he did not even apologize. I told him that as a result his staff had inconvenienced me and he responded I'm also inconvenienced.<br> <br> I asked him to make a solution when I called back now he said \he is fixing it ".. we are still waiting. The least he could have done was apologize and try to make it right first "
