Drgreenfinger.co.za worst customer service

My order took 6 working days to deliver to city centre. I bought 2g for R280. I only got 1g. I let them know. I.lost more than 50% my order. 1st they were going to investigate. No feedback. I asked.the same question more than once. They don't read properly and don't answer. Then they said the packhouse will contact me. Nothing!!! Worst e-commerce site and customer service ever.
