Online Orders : Worse Service Ever

Requested change of delivery address to my workplace, and upon follow up on order I am told the order will take 5 days, but the Item is in stock which should take 2 days according to the information on their website. I spent 20 minutes for 5 days now, of which I had to cancel the order on the 5th and decided to apply for new contract personally. I cannot proceed with the new application because they are failing to cancel the online application I n order to allow the system to process the personal application. Every call I am promised a call back which never happens and need this online order cancelled to allow the Vodacom World guys to process my application
