Terrible service

Jackery use them to collect batteires to be repaired. They don't contact us in advance to let us know their estimated collection day and / or time - their guy, Mokone, simply arrives at our security gate and phones me. I told him I needed to put the battery into the box and print the waybill, can he wait a few minutes. He said he cannot wait and proceeded to argue with me for two minutes (in that time I could have had everything ready for him). He said he will come back Monday - what if we are not here Monday? They call themselves "the Best Courier Service in South Africa" - what a JOKE!
