On XXXX and XXXX someone logged into my WellsFargo online banking. They added overdraft protection to 2 accounts, they did not change password or make any other changes that I know of. 

They logged in again on XX/XX/XXXX and made 10 " Bill pay '' transfers. 

4 transactions from " Business line of Credit '' account. 
Transactions were in amounts of {$990.00}, XXXX, XXXX, etc XXXX from " XXXX '' account, however since it had no money, the overdraft protection kicked in and charged the transactions to the credit card. ( same transaction size pattern as above ) All transactions were made using " Bill Pay '' feature, XXXX payments were made to account called " XXXX XXXX XXXX XXXX XXXX '' ( i don't & haven't had XXXX accounts in >20 years ). 
4 payments went to " XXXX XXXX '' account. 
Total withdrawn : XXXX My Wells Fargo accounts had minimal usage in terms of $ value or frequency prior to this : " XXXX '' : XXXX usage in last 4 years, {$40.00} balance. 
" Business Checking '' : Minimal usage ( 3-4 transactions a month ), $ XXXX balance " Business Credit card '' Credit limit XXXX used {$1500.00} " Business line of credit '' Credit Limit XXXX used XXXX Multiple calls, MANY HOURS of speaking with rep after rep asking to speak with someone with decision making authority, Wells Fargo replies with XXXX XXXX We deny the claim. based on our research the transactions were made through secure online session by you or someone who had your authority. Based on this information, we determined the transactions were authorized. '' I fail to connect me logging account before and after the occurrence proves that It was me and not unauthorized transaction. 

I dont know what to do as I cant take responsibility for XXXX stolen from WellsFargo via loans using my online account access. 
No one had access to my home or my computer, if someone did, they certainly knew their way around payments and thresholds ( {$990.00}, {$990.00}, etc ) not to trigger any alarms.. 
Saying " we didn't find any unauthorized access, so it must be you '' is a terrible answer. 
The occurrence is a FACT, 6 payments to same payee, 5 min apart, all just a few cents under XXXX From accounts that haven't been used in years, VIA OVERDRAFT Account that was activated just days prior on accounts that had minimal usage in recent time. 

Immediately followed by 4 payments to different payee, using same tactic ^ If THAT doesn't set off any alarms and doesn't OBVIOUSLY look like fraud, I don't know what does Please see excerpt from Wells Fargos official rersponse.
