Vodacom the worst service provider in south africa

I have been a loyal customer of Vodacom for probably 20 years and never had a problem until October 2018 when I completed 3 of my contracts and took out a data only contract on each of the 3 phones. My monthly bill was always R5000 per month and should of dropped to R1700 from October todate but the bill is still R4500 per month. I stop payment the account in January 2019 as no one not even your robots could sort out the issue. I have emailed what my account should be to ********** who was also going to sort out the account over two months ago and yet another one of Vodacom’s inefficient people I have a list of emails and people I have spoken to after holding on for an average of 1 hour for someone to reply and then you send an email and they don’t have authority or it’s now a problem cause I have stop payment it or they don’t want to loose their data deal...it’s very sad how many inefficient people can be in one company and my absolute best is robot after robot then an hour later a person who can’t help but the manager will return the call hahahahahahaha what a joke.. don’t use Vodacom they have become the most inefficient company and not cheap and will lie to get a deal!!!! So Frustrated!!!!!
