Contact Betterment Corporate

On 22 October 2019 I noticed my checking account was overdrawn by 8,000. I immediately contacted my bank. The bank advised Betterment withdrew 11, 257. 10 I advised the bank Betterment was supposed to conduct an indirect transfer from my IRA and not my checking account. After spending an hour with the bank, they advised me to contact Betterment. Betterment blamed the transaction on Bank of America. I then asked the representative to make a three way call to discuss the way forward. The representative kept advising me for over 15 minutes the reason why the transaction happen and refused to contact my bank. Both parties (Betterment and Bank of America) kept blaming each other. I wanted all three of us to talk instead of me calling each representative back in forth. it took me over 15 minutes to to coax the representative. After both parties talked, Betterment stated the following "Unfortunately, the in-kind transfer of your assets via the ACATS process has failed. We received a message that this transfer was rejected because you had entered an incomplete account number when submitting the transfer. It seems that you had typed in a 4-digit account number, but a complete account number for a Bank of America account would be 8-digits long." Since the numbers were incomplete and was rejected by BOA, betterment tried to take the funds out of my checking account. This is unacceptable and I should not have to talk a representative for over 15 minutes to make a third party to my bank to solve this solution. This is my first week at Betterment and I will be withdrawing my consideration as soon as this transaction is complete. I am going to Vanguard where people are much more professional.
