Bad Service Received

Service order ********** 251 I am experiencing problems booting my laptop. I Google searched your customer care. I called in they gave me the wedge tel # ********** . That # just keeps u on hold and then cuts off after a few minutes. I tried calling 2 days no luck. I visited the wedge. When I spoke to parts manager he mentioned estimated costs but failed to tell me they deduct the R200 assessment fee from service bill. I left my laptop. I did mention that their tel line not working. But they did not seem interested in that. They said repair would be a day or 2. That I must wait for their service repair email to give go ahead. More than a day has passed. I cannot call as their # does nor work. I called customer service. Was on hold for about 10 min's. They said now Monday. They said they would get mcCallah from the wedge to call me back. As yet nobody called. Very frustrating customer service. Urgent that I get the laptop repaired and returned as I need for work urgently. Please advise
