No confirmation of delivery

Very disappointed with RAM couriers. I was expecting a delivery yesterday. I received one phone call at 10:00 (no message/ notification of who the call was from). As I was in a quick meeting I could not take the call. I phoned the number and left a message on voicemail. I spoke with an agent over the phone after I logged a ticket on the website. Got hold of another agent on WhatsApp at around 16:30, who told me to expect the delivery today. When I followed up again this morning after no communication, I was told by another agent it will now be tomorrow. So I have to sit in my office for 3 days straight, not moving between 08:00 & 17:00 or heaven forbid not answering my phone. Then a delivery can take 3 days. I still do not have received any confirmation of the delivery date...after I requested that my query be escalated. To RAM- I did not choose you to deliver my package. You were assigned to me by FNB. Take note that other service providers in your space do a much better job.....very disappointed....
