Not happy with the service i have received from old mutual

I have joined old mutual years back and thought they were able to deduct from my account since there was no communication sent regarding them not receiving their payments.I have 4 policies and now two have elapsed due to no payments.I went to their branch in Midrand to find out why and even showed them my bank statement which proves that they have been debiting and I was advised that i was ****med as the payments was not coming through to them.I am really disappointed as i was not even assisted and no one was willing to listen and understand my concerns.It is really sad that an amount of R250 was being debitted every month with a reference that showed old mutual but no one was willing to understand and help me.Not happy at all with Old mutual.All i wanted is for them to just investigate that debit order and reinstate my policies.And it really ****es me off that i haven't received any communication to alert that they are not receiving any payments from me then got an emails when my policies elapsed .I wasn't even aware that payments was not going through to them.
