Poor customer and satisfaction service

To say I am frustrated is an understatement, I am fuming and furious because of the service we are getting from Paxi. the first mistake was made by the lady in Pep VR Mall I told her the parcel is going to Arcon Park in Vaal and she decided to choose ArcornHoek mall . due to the sms being delayed when I realized that she chose the wrong shop I went back to the store the following day, had to forfeit my lunch at work because I wanted to avoid the parcel going to the wrong destination, when I got there I was advised that I need to call Paxi there's nothing they can do on their side, I did as I was advised and the parcel was rerouted and expected delivery date was the 13th as the parcel was collected on the 1st of August.so my client calls me yesterday that she didn't receive the collection sms yet.I become pro-active and called Paxi a few minutes ago to enquire about the parcel only to find out it was delivered at the initial wrong address on the 8th of August, so now they are re-routing it and telling me that my client will have to wait for another 7-9 working days whereas the fault is on their side. they are not expediting the matter as a fault was on their end, we will end up losing clients for our small businesses because of them yoh their customer service and customer satisfaction is poor.
