Worst service I've experienced from a courier

I was supposed to have received a package on a Monday - received an SMS from RAM regarding this. Nothign was received and when I used their tracking site, the package status was "UNSUCCESSFULL DELIVERY IN Cape Town - Unavailable Business - Contact Not Available". I called and they said the courier couldn't find the office to which I told them he would need to call first because there is no way to get to the 6th floor where I work without an access card or authorization from. I was told the driver would be informed of this and call before delivery on a Tuesday - no call came. Same tracking status on their site. I then called again. Came in on Wednesday morning and called the centre, spoke to a Mpumi who insisted the driver had called me and this was untrue. They claimed my number was unavailable yet there was no record of a missed call on my end. When I asked for a reference number she said I must use her name as a reference number. I'm no quality assurance guru but surely any good call centre has some of way to track individual queries than just taking the down the agent name? I then asked to speak to a manager and she put me on hold until I eventually had to drop the call.

Very unreliable service, poor internal processes and *********** personnel. I've used a lot of couriers before but this was my first time with RAM and never again!
