Worst courier service I've ever dealt with.

I've experienced the worst service from this company, it's the worst courier company I've ever dealt with. I ordered a phone with Telkom and it was approved, they were supposed to deliver first week of June but they keep returning my phone and say they don't find me. Today a guy called me and i confirmed my address. I got an sms that Nkosikhona Meyiwa is coming to deliver but shortly after i got another message stating that they can't deliver. They did not even try to contact me. I'm very angry at this point. That's why i prefer courier Guy, Sibonelo from courier is always efficient not this bull**** company courierit.
