Death claim not attended to receiving calls to speak to deceased

My mom had an account with PnP , she passed away on 24/01/2025. I went to PnP Southgate on 3 February to inform and ask what documents they need. Which I took back on 14 when I had everything the lady was do kind called the insurance department was emailed documents which I completed the death form(the was 1 for medical which we didn't do) I didn't have the smart shopper card and told them I would do it at another mall. The next day some agent called, I told her my mom passed away and that I was taking the forms that same day to trade route PnP which I did . The staff member did scan and email showed me proof that it was emailed. During the week of 17-20 saw sms on my mom's phone that she's in arrears I took a chance and called the number I got through. This is when I found the number for RCS that PnP stores have on system and the one at RCS are not the same and resend it to *** same day.On 28 week later a guy called to tell me they need the medical form to be completed which I explained him my mom died at an public hospital Baragwanath (the biggest hospital in Africa) at night I must go and look for that doctor to complete a form. I told him will send through the documents we got from undertakers which has that information on which I only did on the 1 March, a lady also called to ask for documents. On the 3 March , yesterday a guy called and asked to speak to my mom by name. I informed him she passed away and that I emailed the documents , the same after someone called again asked by name for my mom but the call dropped (that the other issues the lines always gets dropped from there side wasn't the 1st time). Today I got to calls that got cut so far and the always start with this numbers 021 832 22... I'm asking from the bottom of my heart that you guys get this right and put a note that she passed away and attend to matter it's upsets me to get this calls I'm still in mourning. The other institutions that she had accounts only asked for her death certificate and worked with it. I'm in no position to go look for a doctor to sign or complete that form , then you should get your staff to do that(did you in form her that on her death her family is required to complete a medical form incase of death when she was given this account). Absa , Fin choice, Capitec all accepted the notice of death which includes medical part that was signed by the doctor or nurse. I'm not too such what's the hold up . Soon we will be getting sms that her account is in arrears. As it is on 19 February we got sms from PnP ref *** for debit order to be paid. On 14 February her Customer Protection Insurance was cancelled, I went through her phone and saw on 3rd sms was send that it will lapsed 2 days after her funeral. I only dealt with her affairs from that week after her funeral. My name and contact details are on the details.
