No delivery after 7 attempts

<p>We bought an item on Groupon and it is supposed to be delivered by Dawn Wing.</p> <p> </p> <p>I phoned them after the first failed delivery and they took my details but no one contacted me, I then got an sms the next day saying that the courier guy is just 7.5 km away but with no contact number attached. I drove home like a hooligan as my office is over 15km away but missed him. They then made an appointment for Monday the 10th at 12:30 but no one showed. I told them numerous times that they have to phone the numbers provided as it is a security estate and we have to open the gate via our cellphones. They just wait at the gate for a while and then leave. There tracker system shows that they visit our house almost everyday but that delivery failed and they will contact us to make arrangements.</p> <p> </p> <p>We buy online a lot and this is the only delivery company we have problems with. Don't their drivers have cellphones to contact?</p> <p> </p>
