Very bad service at DPD Laser courier company

I had a parcels that was supposed to be delivered today by DPD Laser courier company. When I did a follow up in the morning I was told that my parcels are on the floor and I asked them if they are going to deliver and there was no answer. I followed up again around 11 and I was given the East London branch number. I called them and they told me that they'll call me back in 10 minutes and the lady had an attitude towards me. I went to DPD Laser to pic up my parcel and I was told that the driver who was supposed to be delivering my parcel was not available today. This company is working with Dawn Wing and I thought they had improved. Their service is very bad.
