Poor service from logistics company

I ordered online and Buffalo was the company assigned to deliver my package. They received my on the 15th of December. The driver Papa Vafana only tried contacting me vid WhatsApp and when he didn't get ahold of he he didn't try any other means.

On Sunday the 21st I decided to download WhatsApp. I got a message from the driver and when I asked him why he didn't try to call me directly he told me it's his family time not work time.

I emailed buffalo logistics using ***. they are yet to respond. Used their WhatsApp line *** and I'm yet to get a response from an agent called them directly on *** and all the IVR says is I'm caller no then doesn't say the number then says thanks for your patience. Then after a while it tells me the agents are busy and I should WhatsApp them.

I am really frustrated as I've been waiting for my package and I am not getting through to this company. All their channels are useless including their drivers.
