Empty promises, bad customer service

Same delivery order was made and paid the fee, due to strike I called customer service to change the delivery option to collect at my nearest pick up point which is N1 Big Bird in midrand, I spoke to 3 consultants first 1 she said she can nitreschedule at all it’s not possible,the second one said he can only do that once the item it’s reaches the Hub once I get an sms or email I must contact them I did that but nothing happened, I called again she said the driver his on the way she requested the drive to call me, no 1 called me but when I track my order it’s saying I was contacted and was unable to take my order , but I was waiting for the order at work since in the morning I even go extra miles to this order atleast if they can not make a delivery because of strike let’s send it to pick up point I will go and collect, the consultants always promising but they don’t deliver, you sends emails no one will reply
