Worst service ever

Finchoice's customer service is a nighmare.. Finchoice's finance system/department is the worst. They don't debit the installment on the debit order date and I always have to call to tell them to process the debit order. It happened again today and I spoke to the most unprofessional, unattentive and sarcastic Agent. She kept responding to what I wasn't asking because she wasn't listening to me. She didn't even bother to check my profile to see what's happening but was just ralking and talking to a point when she said she can't give me answers. All I wanted to know is why is it that finchoice doesn't debit, why have they listed my account as behind with payments whereas my account is up to date and why my installment increased. She couldn't even make an effort to check and advice accordingly. This agent called Sisanda was super unprofessional and doesn't deserve to work with clients.. i asked her get someone to call me since she couldn't gove me answers and she says her saying okay doesn't promise anything.. I'm utterly disgusted by the this treatment..
