Flexi club

I have been having such a difficult time with Flexi access. They have listed me as a missed payment when I checked my credit profile and when I called them they said no payments was missed. This affects our scores. Now I done a booking and it asked for a CO payment which was done but guess what it is asking for more money which no one from Flexi club can tell me why I need to pay more. A real bunch of ripoff. They need to have competent people who can assist and give clients a call back.
