Inefficient service from Sanlam Sky

I requested refund on sanlam sky based on erroneous deduction on my payslip.The policies concerned were cancelled on 30 June 2022.The deduction was executed on 15 July 2022 on salary.Sky e mailed refund form and were completed and e mailed on July 25.The automated confirmation indicated 5 working days to receive refund.On Monday 1st August I called as 5 days have passed and was advised that a copy of ID,bank statement ,proof of deduction are needed and were e mailed.Tuesday was advised that payment would be made on Wednesday evening or latest Thursday morning and no refunds.I never had this delay from sky previously and is infuriating.
