Vodacoms incompetence

Despite requests over many months and dealing with numerous people at Vodacom, their service franchises they do not email invoices as they used to. They now come up with fictitious invoices for services they do not provide and threaten with arrogance to cut us off. There is not one person that truly wants to sort this out. If they have a email issue then send our invoices with a courier ( We pay R4000pm). We have spent hours and wasted time trying to sort this and no longer.am prepared to fight this wall of incompetence!. I told Vodacom we are no longer prepared to waste further time and will terminate all our accounts and move to another service provider prepared to sort the issue.
