Disgusting conduct by Homechoice

My mom had an account at Homechoice,and she passed away in March 2019.She passed away before she settled her account, and apparently she gave them my cellphone numbers,which I don't have a problem with because she was partially deaf.I received an sms from Homechoice asking me to make a payment on my Homechoice account,I called them only to find out that it was my mom's account.I asked for the outstanding balance because I wanted to make a payment,and they refused to tell me the balance. I then informed them that my mom passed away in March,and I was given an e-mail *** to send a copy of her ID and Death Certificate which I sent.For the past 2 days,I've been receiving calls from VVM attorneys asking me to make a payment.My question is,how do you hand over someone who has passed away,and her documents have been sent to you.Homechoice, I do not want to receive any messages from you nor from VVM,because you are harrassing me.
