UNPLEASANT, UNFAIR, INHUMANE AND PAINFULL TREATMENT BY OLD MUTUAL

In November 2023 I app**** for premium holidays on funeral policies I have with Old mutual. I was sent an sms on 5 December 2023, informing me that i should make sure that there is sufficient funds in my account from 1 January 2024 as my holiday premium on my policy where I pay 415.69 was ending. This did not bother me as I had more than enough money in my account. Again on 5 January 2024 i was sent the same message, this time pertaining to my other policy and the premium is R545.25. The sms asked me to ensure that enough funds are available in my account from 1 February 2024 for premium to be debited. Then on 2 February 2024 i realized that no premium was deducted on 1 February 2024. I then went to nearest Old Mutual branch to enquire. To my surprise, the R415.69 that was supposed to be debited by 1 January 2024 had also not been debited, and it had lapsed. The premium that was to be debited by 1 February had not been debited also. This caused me a lot of frustration and anxiety as they could not explain to me why my account was never debited. I was then asked to pay cash of R1662.76 to have the lapsed policy re-instated which I did with a heavy heart on the same day. Also I paid cash for my other policies. Proof of payments were presented to the Gateway branch and were uploaded onto the system. To date, Old mutual claims that payment for the lapsed policy has not been received. When I enquire, I am told, i put S instead of a 5 on the policy number. Honestly, cant they pick up that this was an error? What do I to have this resolved. They keep on sending sms's saying I should pay. This policy covers my parents in an unfortunate event when I happen to lose them. If that can happen now, what will I do??. It was not my fault in the first place that they did not debit my account now I have to go through this heartache. What do I do so that the policy reference number can be corrected. I know they can see payment cam from, but just do not want to pay should anything happen to my parents. Please can someone help me. I am highly depressed and frustrated.
