Inconsistency

I have renewed my service plan with MFC after they called me, spoke to the lady by the name of Rebecca. i was told that my next debit order start next month, then yesterday i noticed that the debit went off, then this morning i called to ask for the refund and question why it happened against what i was told, the lady who i spoke to on the phone told me that she cant trace the call that i received on the 09 September 2022, she cnt even see that i have just renewed the service plan, the service plan number is too different with the one i have on new documents. i need to understand if i was ****med or what. The lady i spoke to today on friday is failing to help me, she even failed to transfer me to the relevant department, the finance department also failed to help me, they just transfer me. No one is available to assist me, i was transfered to 3 people but still no help.
