Worst service EVER!!!!!!!!!!

This is the worst telephone system we ever used. Bad service, unfriendly staff, the system are more offline then online. This system has the most technical errors that we have ever experienced. We want to trough their useless system in street so that a truck can smash it to pieces. When they came to introduce the system, they were here twice on daily basis, after the contract were signed, and the system was installed and not working properly, we never saw one of them again. After a month we finally got them to send their IT team to assist us, went well for a week and then we are back to square one, dead telephones. If we could undo the change between systems, we would have done it already. If their head office experience technical problems, so does every single one of their clients as well. This is very bad for our business image and our cell phone bills are sky high. We do not recommend their services to anyone else. Worse than worse service. Unprofessional service.
