Double deductions on premium

Double deduction on premium. Tried to submit documents, then emailed documents, to make sure everything is in place. Then again tried to submit online. Happened the same thing last year. Could not reverse transaction. They corrected it by not taking premium in Febr. His year wanted to prevent it, and again it happened. I want my money back into my bank account. We work with budgets. Tried to phone and it took all my airtime and was unable to talk to somebody. The bot is frustrating the living daylite out of me, as you cannot communicate with anybody on whatsapp. And if my salary increased so mutch would you not think that I will contact you to upgrade myself as I will want better benefits. Please not next month before next week I want my money back.
