Utter bad Customer service

Since February 2019 we struggle to cancel my diseased fathers policy no ********** 9279. All required paperwork was e-mailed. They even went so far as to issue a new police no ********** 7767 but on this policy the ID no was wrong so they had to cancel this as well and issue a new policy. Since April I was phoning their call center asking updates on this every time talking to a different person Mnr Buleno who worked with the last police will phone me back till today never happens and I cannot get hold of him. on the 1ste of May both policy's was deducted from the bank account, now I'm paying for 2 policy's not wanted.
