Parcel not delivered

Good day,

An urgent document was sent to me from Nelspruit to Polokwane yesterday. When the courier got to my gate I had gone out to the hair salon at the time. I asked the security to let them in to drop the document off at my apartment, but the driver left as they are not allowed to leave a parcel without a signature. I got back 20 minutes later and I called their head office who directed me to their local office at ***. The number rang several times without being answered. Eventually the gentleman who answered the phone promised me that he'll ask the driver to turn back.

That was before 12 midday. Around 3pm no delivery was made yet. I called the gentleman again and explained to him that I'm not home next week and it's important that I receive the document today and again he promised that I will receive it today. I waited until after 5 to give them time, tried calling again and there was no answer. I paid the courier so that I can get the document on time. Yes they came, but I was not going to sit around the whole day waiting for them as they don't give time arrangements. My worry is that if they are not working tomorrow I might struggle to get it as there will be no one at home next week.

Please help me out.
