Bbdaily — Harrassment by goons and false promises by customer service agents

I have asked for a callback 100 times now and everyother agent keeps on lying or sending the same response that I will receive it within 15mins however I see it's been 6 hours.

My mother is severely unwell and old. Doctors prescribed her not to force her to wakeup when she sleeps unfortunately your agents are too illiterate to understand that.

From last 3 days, my mother is getting harrassed by the delivery agent and his manager. When day they come at 7am rings the bell and stand there talking to eachother. What's the point of ringing the bell then?
Then they clicks pictures of my flat and tampers the outer package and clicks the pictures again inside the flat.

First of all, how dare he that he clicks pictures of my flat?
Secondly, my mother kept on asking not to ring the bell as she is severely unwell but the manager and the agent both didn't even bothered to reply her back and kept on talking to eachother for 5 mins standing in my door.

I have clearly mentioned not to ring the bell, then how dare he do that?,

Seeing an aged lady staying there along doesn't gives you the chance to harrass her. How come after asking him not to ring the bell, he keeps on doing so and so unbothered to answer my mother every morning?
Ordering from bbdaily doesn't allow you click pictures of my flat or harrass my mother early morning.
