Fed up

I had an overdraft facility which has been paid up, but FNB handed me over to Brooks & Luyt Attorneys. Now Brooks & Luyt Attorneys are spamming me, after I have phoned, smsd, whatsapped and emailed them telling them that the account has been paid up for 6 months already to no avail they phone me at least 5 times a day. I am sick of this. Sometimes they phone and when I answer the phone is put down by them !
