Stay away from this shady/unethical business practice

Stay away from this shady/unethical business practice. Complete ripoff on materials and billable time. The team arrived have don't required parts, so they drive around Joburg to source items (taking their sweet time), claim they were "only" away for 30mins, while everyone sits and waits. When asked for a breakdown of material cost, I was completely ignored, all they know is to send you invoice. Zero management intervention or customer care. Pathetic!
