You ruined my dads bday with your mistakes

Worst experience ever. I cant believe how you messed up my fathers birthday today with your many mistakes. Im totally shocked. And instead of fixing it, you opt to just cancel it cause your one mistake after the other made it too complicated for you. Order nr 874629q. You messaged me this morning at 9:10 to say the items have been picked and on its way. Then i tell my stepmom that they must please stay home to receive it between the original times that i booked this morning. I then get a call from a lady saying that your stupid program somehow caused that pickers in JHB picked my order, eventhough i clearly placed the order with my fathers cape town address. By this time ive already told my parents to sit and wait for it. So i asked the lady on the phone if this is gonna cause any delays and is there gonna be stock issues cause ive now already arranged that they sit and wait (on his effing bday). The lady responded that no there wont be an issue (listen to your call recordings!) and that she will quickly get it changed to cpt and get the order to my dad. Needles to say i got no update so by 1.45 i called your centre to ask for an update cause no one has arrived, and my parents are ****** wasting their time waiting, when they could be out enjoying his bday. After explaining to the lady what transpired this morning in your company with the ridiculous jhb/cpt issue, she then let me know that the guy she spoke to said its been repicked and on its way. I then told her i dont trust that persons answer cause he obviously just checked the system instead of physically checking. (The system said since 9:10, that its been picked). I was then assured that its on its way. I also got an email from the lady stating that it IS on its way. I told her that they must deliver to the neighbours cause my dad them want to leave. Then at 2.30 i get a call where she said "oh you were infact right, they did think it was repacked in cape town, but it hadnt been. Infact now that they realised it and wanted to go get it, the closest makro is out of stock, so i went ahead and cancelled the order." You know, if it was my company, id of realised how badly i messed up with false confirmations, promises, and subsequent planning from the client, that i would of sent someone to another makro where there IS stock (i checked... montague gardens have), to fix all the frustration caused. Shame on you. This was my first order with you. And definately my last. Sorry mom and dad for wasting your time. I hope Dad still had an ok bday. Please never ever use Onecart. Their mistakes and then subsequent lack of wanting to fix it, is shocking, and im sorry that juvenile attitude ruined your morning.
