Shocking bad after Sales Customer Service

When i was emplyed at Vodacom for 25 yrs, it was absolutely necessary for me to defend bad publicity regarding customer service, etc. Now that I no longer work at Vodacom, I understand why so many people complained about their shocking after sales customer service. I upgraded and changed my sim from data to voice & data at the end of September 2024, and required a new sim card that I did not receive despite being promised one. Needless to say, I was paying for a service which i did not use. To add to my woes, whenever I called I was shuntered around from pillar to post. Finally yesterday, I was advised to go and purchase the sim card which I duly did. Earlier on today I called CC and spoke to a young man for 37 minutes! I needed to change the user name and the CC agent could not spell nor understand my request at the beginning of the call and kept putting me on hold. He also asked if I got married because of my request, "I kid you not"!! He then gave me an email address to send a copy of my ID which was incorrect as the email returned undelivered. At the end of the call I requested my service request number which he could not provide because there was something wrong with his computer. Regretfully, my request has not been resolved nor actioned because in my opinion, the person that tried to assist me does not have the necessary skills and hence is not ready to assist customers. Vodacom needs to ensure that Agents are properly trained and have the right skills to assist customers. Publishing reports that Vodacom has millions of customers does not make them a great Telco to deal with. I should of cancelled my contract at the time and regret extending my contract for another 2 years.
