Disgusting Service

I have been a Nedbank customer for 5 years ,paying my premiums with no issues ,In January 2020I missed a premium ,normally when they miss a premium ,they make you aware ,so they debited double the amount and I was not aware ,the funds were insufficient and therefore the debit order bounced ,they immediately lapsed my policy and I called them to rectify this ,they reinstated my policy and told me that the waiting period would be 6 months ,I told them to use a different account to debit and should always debit on the 25th ,they failed to debit on the agreed date and they randomly debit on their own dates leaving me with a bad account for failed debits ,I called them on the 1st of April 2020 to find out why they did not debit ,spoke to their call centre agents with a stinking attitude towards customers ,I spoke to Solomon Nxumalo ,instead of resolving the issue ,he turned this into a debate ,made me sound like I was stupid and muted me for some time upon requesting to speak to a manager ,so I'm sitting with a lapsed policy ,should anything happen to me or my loved ones ,I won't be covered because of a company that belittles customers , I have been paying this policy for 5 years with no issues ,now I'm being treated like dirt .
