Switch telecom has no backup service that will cost your company money

I joined switch telecom about 2 months ago and there has been a couple of small problems. Our Cape Town phone lines went down 2 days ago. We logged a call and since then cannot get hold of this company. We have tried to call and e-mail. Anyone who has a business knows the loss of sales by not having phone lines for 2 days. I contacted the office which had a automated machine saying that all staff are on a course. This company clearly has no idea what customer service is and I would strongly recommend that your due diligence is done. I am absolutely appalled
