Poor service

I was unemployed for a month I’ve made arrangements with Finchoice because I then started a new job and arranged payment for 31st October they deducted way before the time even though I’ve communicated so many times about the date , I called in and no one could help me rectify this matter each time I get out through different departments with no help this is not the first time this has happen .no one ever tells you the full details of your loan until you pick up the phone to enquire why things happen without my consent this is unacceptable and I’ll be going further with this matter
