Poor service

I expected a parcel ( new cellphone ) from Vodacom. On the 12 Dec 2019 the courier company - RAM Couriers send a confirmation sms that the delivery will take place on the same day. They tried to deliver to my previous address. I contacted Vodacom via phone and email to rectify the problem. No one was able to help me immediately. On the 03 December 2019 the same again. RAM tried to deliver to my previous address again. After many calls to Vodacom and about an hour holding to be assisted, Vodacom informed me that the sales consultant (P. Naidoo) updated my new address only on my profile but never to the courier company for delivery. This cellphone was suppose to be a Christmas present for my wife. Now im not so sure if that will happen. I now gave Vodacom my work address. Hopefully I will receive the parcel before 2020!!!
