One Net Express - System Faulty & Service Shocking

We have been with One Net Express since close to its launch and were willing to accept some teething problems. Yet almost 2 years later the solution has actually become worse:<br> <br> 1) The system often doesn't work and our customers fail to reach us without our knowledge. This has and is costing us a lot of business. <br> <br> 2) When we try change the numbers of members on our group it takes no less than 4 weeks worth of numerous telephone calls and emails before they get it right and have removed all the numbers requested to be removed and added all the new ones. Lack of system!!<br> <br> 3) When we are in foreign countries like Germany and the Netherlands our cellphones being on Vodacom contracts default to the local Vodafone SP and we can't receive phone calls unless we manually select another service provider like Orange.<br> <br> 4) Even though we have tried numerous times we do not get any inclination from Vodacom to assist with our issues. Everyone is either passing the buck and we get thrown back into the pool of some help line to hold for another half hour. <br> <br> 5) We were promised the call forward function would work by 2014. It still doesn't and nobody can give us an update on this.
