Absolute Horror Service from Vodacom

This is the worst experience I have ever had with a company in my life, I ordered with Vodacom on the 11th of April, I asked for the delivery address to be changed on the 13th of April and I have called every day since the 13th to confirm that the address is changed as Skynet delivered to the wrong address. Every day when I call after-sales support, the agents tell me it's changed but it takes time to reflect on the courier side. I called Skynet every day as well to see if it's changed, Skynet even sent an email to Vodacom to approve the new address but to this day the 24th the address is still on changed. I called this morning to check on the delivery and Skynet tells me that the job is going to the old address in Gosforth Park, Germiston instead of Randburg, meaning Vodacom has failed to change the address in over a week. Do you know how *********** and unbothered you have to be to fail to change an address in over a week? At this point, I don't think I am ever getting the device because I am not at work tomorrow meaning they can't deliver and I will have to follow up again on Wednesday. This is pathetic service, ordered on the 11th and it's the 24th still no delivery because it's so hard to change a delivery address.
