Parcel delivery to incorrect addres

I am gravely annoyed and disgusted in the customer service delivered by MTN / Velocity as well as RTT Logistics >> I am naming them all as each is giving the other the blame.<br> <br> I received a call on 24/06/2015 from no: *** to assist me in upgrading my MTN contract. In my uninformed mind I thought this call was from MTN but Today I find out that it is a 3rd party dealing on behalf of MTN. Anyways ... I decided on an upgrade to the Samsung Tab4 3GB @ R359 per month my ref no: UV657372.<br> <br> On 05/08/2015 I received a sms that delivery was scheduled for that day. At 10h59 I received a call from n: *** the delivery trying to find my delivery address which he had as Arcadia, East London. I called RTT Logistics on *** to verify the address and give them the correct address myself. I called MTN on 808 number and confirmed the address with them again. Today 07/08/2015 I received a sms again that my tablet will be delivered to me. @11h30 I received a call from *** yet again the delivery guy who is sitting in Arcadia East London with my tablet AGAIN!! <br> <br> Now between MTN / Velocity or RTT logistics >> YOUR SERVICE SUCK!!
