Still receiving calls for deceased from RCS

I wrote an review on Tuesday about above mentioned company. Got a response on helloPeter and a lady called me Ada(RCS complaints department)was her name . Sympathies with the passing of my that my query will be escalated requested that I send documents again including the email that trade route PnP send to the other email address. Was informed that the collections department will be informed not to call the again. On the email it said that RCS would try and resolve within 48 hour or 10 days depending on nature of case(so I took it we fall in the 10 day period)will be updated on the progress. Well I have not been updated , 48 hours was on Thursday, only got response from automated email when I send through documents. Have been received calls still on Wednesday, Thursday and Friday (the one agent had the nerve to ask me to resend the documents again, I refused told to follow up with their complaints department as they are dealing with matter via my complaint on this platform) . So I don't know anymore, who's dealing with it and how far it is . Ada emailed me on Tuesday afternoon to forward the documents she didn't even acknowledge that send got them.
