Terrible Service Received from Sanlam

I’ve been struggling since early August 2022 to increase my Retirement Annuity contribution and switch to a different bank from a debit order collection perspective. I’ve completed multiple forms as requested. On the 23rd of November I received an email from Sanlam advising that me they could not finalise the above in time for the November Debit Order. This after they missed collecting the higher amount in August, September and October. As a long standing client of Sanlam, I expected someone to call me and explain the situation telephonically as well. Sanlam could not service a simple request over the last four months!!!
