Investors continue to come forward in dispute of securities broker Randy Lee Birkinbine (CRD#: 2008599, North Oaks, Minnesota). Namely, Birkinbine, who presently works as a broker and financial planner of Ausdal Financial Partners, discloses four investor disputes. Notably, his clients allege that he committed sales practice violations leading them to sustain losses or damages. Here’s more on what these investors voice in their disputes.
Randy Birkinbine’s BrokerCheck Report shows that a client complained about him in September 2020. Particularly, the client suggested that the securities broker sold unsuitable investments and of causing an overconcentration of their account in certain investments. Because of Birkinbine, the client supposedly experienced $109,000 in damages. This matter is ongoing.
Also, an Ausdal Financial Partners client took issue with Randy Birkinbine as evidenced through a February 2018 dispute. In particular, they alleged that Birkinbine failed to tell them significant information in regard to private placements. It seems that the client needed liquidity but invested in a private placement that did not allow them to receive their assets. Supposedly, the client did not know that they would not receive a return on their investment. For this reason, the client demands $150,000. This matter awaits a resolution.
Evidently, an Invest Financial Corporation client disputed Randy Birkinbine’s representation regarding an insurance product. It appears that Birkinbine may have told them that they would get seven percent guaranteed appreciation. Because of this, the firm settled through making a $25,847 payment to the client.
And in the fourth dispute reported on Birkinbine’s BrokerCheck Report, a client claimed that there was no due diligence performed by Workman Securities Corporation in regard to Quest Energy Management senior preferred notes which defaulted following the client’s purchase. Evidently, the client received $35,000 in a settlement.
