Worst Customer service(Online purchase)

I bought something online that never got delivered despite notifying me that the parcel had been shipped and will be delivered the next day. It's been 4 days now that my parcel has been going back and forth with the courier people. Please ensure that the parcel you ship is delivered and also follow up with the customer (Good customer service). I have sent you emails and you never responded. I wasted my airtime calling the courier and still nothing. I hope those perfumes won't be damaged by the time the courier people feel like delivering them. I am really disappointed with your service
