Dissapointed with first for women!

I signed up with first for women to insure my car ,after finalizing the contract with them ,we agreed that the insurance will be commencing on the 2nd of February , however they didn't brief me that they would be debiting me upon the 1st day of the policy .I then called day before to inform them that the dealership postponed delivering my vehicle and that they should cancel the policy ,the agent assisting advised that the cancellations department was closed and I should call tomorrow at 8 am .The following day I contacted them ,my call couldn't go through,I tried several tines with no luck, later during the day,they debited and the debit order bounced,they then debited after I advised them that they don't debit as we agree on a payment day,the debit orders resulted to my account being over drafted ,leaving me with crazy bank charges,I called the call center again and spoke to the Sales manager by the name of Nono ,who assured that she'd follow up,she never called me back,I had to be the one making effort and follow up ,I called again on the 1st of March and spoke to her ,she said she'll call me back ,she never did,I called again in the morning in the 2nd of March ,spoke to Naomi ,said she'll transfer me to her ,I was on hold for 15 Minutes until I hung up,I'm so sick and tired of all this ,being treated like some sort of *******!I want the bank charges payed.
