SANLAM DEBIT WITHOUT AUTHORITY

I have had issues with my Gap Cover since January 2020. Eventually after receiving shocking service and no Joy from Sanlam I cancelled the Policy. I have confirmation of the cancellation. Then today you debit my account again. With not a single payment but a double payment. This is absolutely pathetic. Are your people even awake at the office? How difficult can this be. The policy was cancelled. I am no longer covered by yourselves so what are you taking my money for?? I do not want you to phone me. I am truly exhausted from fighting with you for 3 months now and cannot deal with another *********** person with poor excuses. I want this rectified IMMEDIATELY
