Icover worst service ever

Worst service ever.

I have an Icover policy with Sanlam since 2018.

I changed my debit order dates and told them and a consultant called to get new details as my policy was going to lapse.

They still debited the old account and I told them they debited the wrong Acc and that account does have funds or not in use anymore.

They responded to say yes they have received the money and I told told that it’s impossible because fnb sent me a debit order failed messages.

This communication is all done by email and different consultants telling me I don’t owe anything to my surprise an email comes in saying I owe money.

Can I have a resolution on this Acc because I am puzzled what to do next.

Your consultant just don’t hear.
