Poor service

I am very disappointed at Buffalo logistics. Firstly they do not give you a time as to when your parcel will be delivered you get the message from the driver when he has a arrived. Secondly when emailing or whatsapping the customer service you don't even get a response the message does not even get read. Then you have to deal with the driver being rude and also messaging me and phoning me on WhatsApp what if I didn't have data then what was going to happen. I am now waiting for my parcel as I was not at home the time it was delivered. I am also angry at the fact you pay for your parcel then you must still pay import tax which yes I understand you need to but why can it not be taken when ordering your parcel and not then having to pay after the fact.
