Bad services from payflex

I am so ****ed off right now because my bank balance is in a huge negetive right now because of all payflex payments that are going off as a duplicate and when i sent them an email all the consultant advised me was its reserved from the bank however she was not listening to me as i tried to explain i already made all the payments myself via eft. There was alot of back and forth going on and when i asked can someone contact me she asked me to call the manager.. Meaning I have to use my airtime to call. This morning i saw more amounts going off making my balance much highet than it already is.
