Terrible customer service from call center representatives

A debit order bounced 25th April on my car insurance policy Ref ***7 because there was no money in my account then miway representatives moved my debit order date to the end of month without letting me know, Call me if changes to happen on my policy. Please stop doing this you must make sure you call me first then I give you go ahead because I am the one paying for Bounced debit orders. Issue number 2, After my debit was bounced I called twice in two different days to arrange manual payment and they told me the Manager must approve the request till today I am still waiting, please send me the reference to pay my insurance manually from date until the 25th of May and they don't change my debit date. Kind regards, Abel
