Disappointed in Vodacom

A lady from Vodacom sales recently called me to upgrade my data sim and offer me a free router at the same amount I have been paying. I made mention of my surname change but when the parcel was delivered it had my ****en name on it which didn’t match my id, so the delivery guy from RAM courier could unfortunately not give me my parcel. I then took the time to call Vodacom, they updated the system with my new surname as well as ask for my id copy and marriage certificate to update everything. I was then told that someone will call to arrange another delivery for the router which never happened. I called Vodacom earlier this week and they told me they just received the returned order on the same day that I called and that they would call me on Friday to reschedule another delivery. To my surprise, I today just received a text stating that the scheduled phone call was cancelled as per my request, a request that I however did not make. I am so disappointed in Vodacom and that I have to be the one now following up with them when they had promised to sort everything out. My order number is K***
