How hard is it to fix a delivery address???

Today I decided to try out Vodacom's online store. All I can say is NEVER EVER AGAIN!!!<br> <br> After placing my order, I receive my ref no. to activate the order. Followed the link, entered the ref no. and my ID no as requested and boom, all details regarding my order were incorrect. Wrong tablet, wrong price plan, wrong customer, wrong delivery address. So phoned to have them fix it. After many phone calls wasting my entire morning they send me a confirmation email. All info was correct except the delivery address. Phoned again and they say they will fix it. 10min later receive another confirmation address, still same address appears. Phone them AGAIN and they said they'd fix it.<br> I have not yet received another confirmation email and they promised delivery tomorrow (12 November 2015). I do not know if they fixed the delivery address but I have been in contact with the customer whose details was linked to that ref no. She will let me know if she received her order or mine.<br> <br> If this does not get sorted out, then you guys can shove that tablet where the sun doesn't shine.<br> How difficult can it be to fix a delivery address???
