Bad service and non delivery (Request to deliver a letter)

I requested a service for them to deliver an official letter in the Vaal on the 15th February 2019. They collected and I made payment as it was discussed. Firstly the owner was not calling me he was communication via whatsapp which seemed strange for a reputable courier company. Even when the driver arrived to collect from me I was whatsapped and informed he was outside. No phone call to make the process seamless. This did not raise any eyebrows at first. Then when the driver got to the Vaal I was driving at this point on my way home from work. I get countless whatsapp messages from the owner who is telling me the phone of the recipient is off and the GPS is showing that the area mind you a residential area is dangerous. Fine this starts to worry me and i call the owner. He relays the story and when i ask if they called the recipient he said their phone was off. I then called the recipient and the phone rang and it was on. This means these guys **** and charged me for a non service delivery. I tried calling the owner back but at this point he ignored all my calls and whatsapp messages.

On Monday morning on my way to work I called him and requested my letter back because they failed me and they ****** me. The service was disappointing and I would never recommend anyone to use their services. The owner was disrespectful and even put the phone down in my ear as i was telling him he **** to me and that they did not even make any effort to deliver this letter. This letter is important as it is from the lawyers and it was important for the delivery to be made on Friday
