TERRIBLE CUSTOMER SERVICE

I've ordered 2 contract phones with Vodacom on the 15 August 2019 and on the same day an online agent by the name of Sibongile phoned me and she advised that their courier needs to deliver the parcels where I will be able to sign for. That when I advised sibongile to change my address to my business address, to my surprise on the 19 August I've received a call from their courier guys asking if I'm available at home and I told them that I'm at work and I've changed the address with Vodacom. Then I phoned Vodacom to find out what was going on and the other agent advised me that the address was not changed. She then asked me for my work address and i gave it to her even spell it out and advicing her that I'm in JHB CBD. on the 21 August the courier guys phoned me again and asked to find out if I'm at work and then they confirmed a wrong address that is in Krugersdorp and I told the lady that I work in Johannesburg not in Krugeresdorp and Vodacom was provided with the correct address. The service I'm receiving from Vodacom is terrible and pathetic, such a huge company. I phone again on the 21 August the agent dropped the phone on my ear because i was complaining about the poor service from Vodacom. I really disappointed about the treatment their giving to the potential customer. VODACOM YOUR SERVICE IS PATHETIC AND YOUR AGENTS DON'T KNOW ANYTHING ABOUT CUSTOMER SERVICES REC-***
