Clueless about directions or didn't think my parcel important enough

I ordered a RAIN sim and RAM notified me of the delivery on Wednesday. The delivery guys called me and didn't seem willing even to try and find out where I was located, they kept telling me they were at a SHELL garage but when i told them I didn't know it, they said they would call me in the morning the next day.

Next day came, notification at 8 am. I waited. No call. The day went by and nothing. I called them myself the following day and they confirmed they would come by. After a few more calls, I called the customer care and they told me the parcel was at the warehouse. Meanwhile the drivers keep saying they are coming and they will call me i should calm down. They never came obviously.

Now i have to wait til Monday because of their incompetence. Don't their vehicles have GPS? Don't their phones have Google maps? The address was as found on Google maps yet I still hqve to direct you to my home. Completely disappointed
