Vodacom - the leading poor service cell phone provider

We have a business account with Vodacom which has been in place many years. our sorry tale of shoddy service started at the end of July 2019 when due to a restructuring of the company we wanted to close down a number of data cards linked to the account. of the 9 cards to be closed as at today we still have 4 not closed with those closed having happened over the previous 3 months. in the meantime accounts keep getting issued and to add insult to injury Vodacom marketing people continue to call offering upgrades on the very numbers we are trying to cancel - when I explain my problem the general response has been to hang up !! I have logged a complaint on the Vodacom website - which had no effect what so ever. I have spoken to many many people - people from the customer services department with only limited results. I have asked to speak to the manager in that department, a Nombulelo Thwala but she never appears to be there and has never responded to messages left. I have asked for her number but am told that her number cant be released - a customer services manager who wont give out her contact number - really?? my last person, Khutso Lediga has been the most helpful but even he seems to have thrown in the service towel. I have asked him to provide me with the correct person at the highest level to speak to but alas nothing. if anyone from Vodacom is out there and interested I await your contact. lets see if anything happens - but I am not holding my breath
