Ferns N Petals — Not stopping reminders for a dead person after 5 calls

Hi,
This may be a small concern for you but a big deal to me.
I once sent a gift to someone and that person died a year and month back and ferns and petals still sending me reminders to me send another gift.
I have called them 5 times and everytime they confirmed that its gonna stop.
Now i just wanna know there process of sending gifts to hell or heaven.
Because they are not taking my words that the person they want to send gifts is dead.
Please help me on this
