Annoying

Lousy customer service! At first i was told my contact number was wrong it took them days to rectify that, in the meantime my parcel ended up back to sender, it was sent again and when i tracked it, it was out for delivery but i was never called, again i contacted the customer services i was told the driver says my adress is wrong yet he doesn't call me, i have enquired more than 10 times everytime im told my matter is being escalated
