UNPROFESSIONAL SERVICE RECEIBED AND PARCEL NOWHERE TO BE FOUND

I cant belive what I went through with this company. I asked for a return for one of my parcel and it was booked for collection. On Saturday, a driver called me to say he was outside my house and when I went outsude he was not there. I called him and he said he is coming back in 2 mins, making me wait another good 15mins. I called him back again and he said he was outside my gate, when i asked him to give me the address, it was a completely different address. He asked me to send my location and I told him he should have my address on his paperwork. Eventually he arrived with a white NP200 bakkie that was not branded and he appeared to be under the influence of alcohol. I handed him the parceland he said he did not have stickers to give me, I asked him how i will know my parcel is received he said you will get a message, which I never did. 3 days later, another Buffalo car is at my gate "to collect" the parcel. I explained to the lady that the parcel was collected on Saturday and she was shocked and said it was not booked or scanned. Called the first driver and he seems puzzled, asking me to send my details. WHERE IS MY PARCEL? I a being sent from post to pillar with no answers.
