Unsatisfied service since July

My husband passed away 2nd July...I phoned Supersonic and told them and changed banking details....account still on my name only account no at fnb changed, nothing was done and payment was sent back...on 26 August I paid R400 and sent numerous emails and phone calls to accounts, customer care etc.....they say all calls are voice recorded , I am sick and tired of writing emails and wasting money to call them....no joy BUT I get Invoices and Statements and no sign of R400 paid !! last month spoke to a very friendly person and was told all will be fixed and debit order will go off on 25th October.....Still no joy !!!! This is really pathetic
