Bad service from Buffalo international

On last week Thursday I was supposed to recieve my parcel. They then sent my an sms that says they couldn't deliver my package because of wrong address. I called them immediately to enquire about this because they've been delivering to the same address for almost a year now. Their call Centre agent told me that it's because the new driver took a wrong route. Which is non of my business because they are responsible to deliver my package. How I wish my supplier could always choose aramex for my deliveries., I've never experienced such incompetence with them. Today's its a 5th day calling Buffalo international and they hanging up on me. Can this be sorted ASAP please. I just want my stuff! My name is Lerato call me on ***
