Bad service

We are trying to contact the support at from 7 o’clock this morning we have left several messages no on phoned us back there is no after service at centurion systems they have high calls volumes the whole day. I don’t know how it is possible!! We finally got trough and when finally it was answered by a Emslie and all off a sudden they couldn’t hear us and was cut off we have phoned hundreds off Rands and still no one to help. This is terrible service how are we supposed to sell these products and not be able to help the customers
