Early unauthorized debit oder

Well i have a comprehensive cover with mi way which is due to debit on the 20th of each as agreed when i took cover. This morning the 19th they deducted my last money in their account and i have plans to use it for petrol and other household things...I contacted no way for a refund as i dont have money for petrol to go back home spoke to Nomsa who didn't help and again another consultant who said she will request for me to called back its been 3 hours.my account is has no funds I dont have petrol and the worse the part no one has called me back its been 2 hours waiting. They telling me I should obtain bank statement meaning I should go to the branch during working hours and get statement which is still an inconvenience for me as a client.

I need my money back today as i dont have petrol to go back home its so sad to be inconvenienced like this
