Dishonest Supplier with zero customer service

I contracted Bronwen Tuck the owner of Garden Mechanix to provide a landscaping quote for our garden. She provided a quote of R6500(R4000 a day for labour, R500, rubble removal and R2000 for new plant allocation).At the garden assessment meeting on 10th Oct, I mentioned that she may remove the existing plants for new ones since these could be given to my family who have just moved into a new home. When she arrived at our premises on 28 Oct 2015, she removed some existing plants, planted new ones and rearranged existing pots. She also installed 2 trellises in the garden which was not on the quote. She only managed half a day so she arranged to come through on another day.We then received an invoice of R8129 which we were asked to pay immediately.We requested that she return the plants she took and remove the trellis. She refused to give us a refund for the trellis, and was aggressive and rude. She has no customer service, my advice don't use Garden Mechanix for your landscaping, as she will lure you with initial \good prices"and nail you with an excessive final price. She definitely qualifies as the lady with green \""long\"" fingers as her plants have been recycled from other gardens."""
