I want to file a formal complaint against " My Best Buy Credit Card ''. Today when I received my mail I opened it and I saw " Interest Charge '' for the amount of {$210.00}, then I called their Customer Service Department to try to remove that Interest Charge because I 'm not or was not aware of such " Interest Charge '' I spoke with a lady name XXXX.I asked her to give me some type of Identification as her Employee Id or Last name She said she ca n't provide to me, she says she is part of a Management Team from Tennessee her team Id is # XXXX. This lady instead to assist me she tried toCharge {$300.00} for the balance to paid on full so she could remove the " interest charge : I said to her I never was aware of this Interest Charge of any previous purchases Idone All the time when I buy with this credit card I got free interest until balance is paidoff, So since she did n't want to assist me to remove this interest charge I told her I wouldformally put a complaint against their Credit Card For " Switch and Bait '' with the CFPB Now I see the illegal way to try to charge me extra amount of money without me notice it .Please assist me to resolve this issue I 'm reporting at this time.
