Robloxmountain View has been hitting my account for * months now with charges I have no knowledge. My bank has had me change my credit card * times and on the *th time, my entire bank account was cancelled and was issued a new account and new credit. All was fine for * weeks and just last night while I slept, there were ** charges of $**.** charged to my bank account by Robloxmountain View. I called the bank *** number this morning, cancelled my card and at *:** a.m. I called my local bank. Was told they could not stop payment on those charges even tho they are still pending. I was asked for the *th time to go into the bank and sign a document to dispute the charges. I am a ** year old widow who has trouble walking. I am not only tired but frustrated with this situation. Does anyone have suggestions what to do? Every time I change accounts I have to contact social security regarding my monthly retirement check. This delays delivery.
