Network. Ot working on cell or VPN.

This morning both cell and VPN line not working, on different units, then slow, then intermittent, then off. Could not get into any system to log call. Finally got some connection after 12 and tried to log a call. What a farce! Not admitting to any fault, yet found out from a separate source there is a National issue. Trying to get me to reset phone options which can only be done when I am off the phone. I keep asking what about VPN, but they persist. They did a sync remotely (?), phone rebooted and then had to call. No change. Suggest I take my phone in to a Vodacom office - asked who is going to pay for all the unproductive data use, fuel and work time? And how does this solve the VPN line. This was obviously too much for call centre and call dropped. STILL NOT RESOLVED and not working efficiently.
