Horrible Service

Nimble Group deducted a hefty amount out of my bank account without my consent. The agreement was a set amount every month but they decided to take way more than what was agreed on. I had no warning prior to the deduction and when I requested a refund they are now giving me the runaround and going back and forth. Whenever I ask for an update I always get told that my matter was escalated but with no real feedback, eventually when I heard back from them I was told that it takes up to 3 weeks which was never stipulated from the beginning. Horrible service!
