Poor service

This am my phone was working fine, at about 8.30 am I've had no service from my network provider. I called the call centre and they said they will synchronise my line and should try switching on at 9.30 ... mind you I have reports to submit using my phone. I waited and they called back on my mobile which was working then and the call was cut and no further follow up was done. I called the call centre again and was told a different story. Basically up until now, 12.20, I am without network coverage yet my accounts with vodacom are all up to date.
