Terrible service from useless call center agents

I have a new policy that was supposed to start today on my vehicle, due to incompetence from the call center agents at outsurance incorrect banking details were captured, now I'm left without cover on my vehicle as my old insurance has been canceled.

I spoke to a very rude, arrogent call center agent on Friday regarding this issue, after her useless attempt at trying to see if the payment off, I'm told there's nothing she can do...... At this stage the wrong banking details are still on the system, I asked for her manager to contact me, that still hasn't been done, and worst of all my vehicle remains uncovered..... This is totally terrible service
