Beyers Aw & Van Der Westhuizen land surveyors

I Bought a empty plot in November 2016 and wanted to sub divide the property. We decided on Beyers Aw & Van Der Westhuizen as the land surveyors as their prices were the best. But after a couple of months we realized we made a huge mistake. You can never get hold of them over the phone or e-mail. They seldom contact us with updates and I have not heard anything from them for the past three months. It has been 1 year since the sub-division was lodged and we were promised 5 months. All my e-mails, phone calls and whats-apps are ignored. Would never use this company again and would advise any person against using them.
