services cut off but no one can explain why

4th month in a row our services have been cut off. been to n1 city branch, who say phone data is up, so all paid for bundles have been suspended. call centre says our data bundle for router is up, but that phone data is available? no one can give real reason. and why cut off all bundles when one is up anyway? the other services have been paid for. business standing still since Saturday. waiting for his royal highness Edward the team leader to call us back with detailed info but not holding my breath because it's 6pm already!
