This is the second time that my parcel did not arrive at it's destination

This is the second time that my parcel did not arrive at it's destination. Aramax simply ignores my messages and are rude and abrupt over the phone. They promise to call back but never do. On one occasion my waybill number was duplicated on their system and they insisted that I had sent my parcel to Cape Town, yet I had the waybill copy clearly showing a Durban address and correct postal code. They then went on to send me confidential information of 2 of their Cape Town clients. I received no apology and they refused to accept responsibility. On Sunday I dropped off another parcel in Johannesburg for delivery in Durban. Till date I am received with animosity and Aramax keeps me online for hours without getting back to me. They insist that the waybill number does not exist, yet I have a copy on hand. I believe parcels are being ****** at Aramax. I wish I could give them a zero rating not a one. They are nothing but common ******* and ****s.
