All Phonecalls blocked from the administrator

To whom it may concern<br> On Wednesday evening, 23 March, I wanted to make a phone call from my cell phone and got the following message: Phone calls using the mobile network are blocked by your administrator. For more info, contact your administrator. <br> Thursday morning I send a mail to Vodacom. They informed me that they are not my administrator but RMCS is. I send them a mail as I cannot make or receive any calls from my phone, not even emergency calls. After two hours I sent another mail and by three the afternoon another one. All without any reply. As I am using the phone for business purposes this is extremely frustrating, none of my clients can reach me via a phone call. I had several miss calls as I got the voicemail notification, but I cannot even dial the voicemail number.<br> I am staying alone and this is my only phone. If something happens at my house I cannot contact anybody. I really feel this is extremely bad service as I tried to reach them since early the morning.<br> <br> Jolanda
