Family Plan indicating I reached my Allownace. I am on no Contract with you since 2020. REMOVE FAMILY PLAN FROM ALL 4 SIM CARDS

I had a family contract plan which expired in 2020 for 4 sim cards and this plan is now a prepaid plan. I changed my sim data on my number to LTE. I still have 12 GB left according to my balance but I keep getting messages that indicating I have reached my Family Allowance "BE NICE to the FAMILY PLAN OWNER" I AM THE FAMILY PLAN OWNER!!!! I cant change any limits or access any of my limits to change. Even your prepaid packages are falling apart. Please Remove the Family Plan settings from my Name. I have no more contract with you. If this continue I will remove all 4 sim numbers from Telkom and seek a new provider. My sons card haven't been able to load data or airtime or even make calls for months now. USELESS
