Business ProfileforBConnected

I made an overpayment of $321.22 to BConnected on March 29, 2022. The payment was toward my healthcare benefits and was made through the company's online banking. I contacted the company the next business day to notify them of the overpayment and inquire regarding my refund. At that time I was told I would be issued my refund back to my bank account in 3 weeks. As of June 20, 2022, I have not received my refund. The website says I was issued a refund on May 9, 2022 but doesn't indicate the payment method and I have not received a check, paystub adjustment or deposit to my bank account. I've contacted BConnected over 10 times via phone and once via online chat regarding this issue. They are unable to tell me if my refund will be posted to my bank account, processed in my pay stub or by check sent in mail. Every time I speak with a customer service representative, I am told the "issue" is being looked into and I should receive another call back in 3 business days with the update. If I attempt to escalate the call to a supervisor, the best they can do is tell me they will "expedite" this "issue" and call me back in 2 business days instead of 3. It is unacceptable to wait over 12 weeks for an overpayment refund and for a company to not divulge information on the status of my refund.
