NOT FOLLOWING INSTRUCTIONS

I have always been very happy with Bonitas but their administrative process as always let me down i sent an email last week asking for them to change payment details for January 2025 , i just got an email of them confirming that they have changed to this month. I am very disappointed with the lack of attention to detail as this instruction was even written on the change of details form. I need this done properly before the 28th of i will have to cancel my membership because what's going to happen is that they will debit me this month and my company will also take their premium so i will be paying twice...PLEASE RESOLVE THIS ... PLEASE CALL ME ALSO SO I CAN BE SURE ITS DONE
