April Double deduction

Old mutual has deducted twice on my account on the 22nd and 24th respectively, I alerted them about this error on the 25.04.20. The person who answered the phone said it was error that happened to all their clients, they were aware and will reimburse everyone the following week but until now nothing has been done. They were professional enough they would have sent an courtesy sms acknowledging the mistake and reassure that correction will be done on a particular date. Since they are taking advantage of us, I need my money ASAP..
