Telkom suspended my lines because of their own ineptitude

I upgraded my kids' phones in March. On the 15th of April I suddently got a message to say the lines were being suspended as my bill was above my credit limit. I immediately got in contact with them and it transpired that when I upgraded the lines, the sales consultant failed to load the new credit limit. Since then, I have spoken to at least 20 consultants. Each one promises to escalate to a team leader, who would be able to unlock the lines. Going into a branch is pointless, as they just phone the number and you speak to the same people. It`s been 4 weeks. My wife and kids have no access to phone OR being phoned. Thank God for a Vodacom modem, so I can at least get in touch with my wife on Whatsapp when I need her. My debit orders go through diligently. I even paid an additional R500 into the account so that it gets below this imaginery credit limit. I am at my wits end. The last Case Number I received (yesterday) does not exist on the system today. Nor does any of the other 5. There is nobody you can phone. All you can do is leave a message on the app and hope they phone back. I have 4 separate lines with Telkom and will cancel every single one as soon as I possibly can. It is without a doubt the worst telecom provider in the country.
