RAM worst Courier Service

If I could give RAM Couriers a zero star rating, I would have done so, unfortunately this website won't allow me! On Monday morning, 03/06/2019 I received an email confirming delivery of my package. I noticed that my cellphone number was incorrect. I immediately contacted RAM to notify them of the correct cellphone number. It is difficult to find my house, so I was afraid the courier would need to phone me, since courier companies refuse to invest in GPS. The message was not given through. I complained on RAM's website. On Tuesday morning, 05/06/2019, at 8:14am, I received an email that my package would definitely be delivered today, Tuesday, 05/06/2019. At 13:51, today, Tuesday afternoon, 05/06/2019, I was informed by phone call that the package would only be delivered tomorrow, Wednesday 06/06/2019. Which means that three days of my life I had to put on hold, since RAM can't find an address or update details when a customer request them to do so. I have to cancel a very important meeting that I had for tomorrow, because RAM can't find an address. Worst worst couriers imaginable. If you are thinking of opening an account at a courier, do not consider RAM.
