Abstract: Systems and arrangements for evaluating and decisioning refund requests and monitoring of overrides of refund decisions are presented. In response to receiving a request for a refund, the system may identify one or more sources of data from which to extract data to determine a decision regarding the request for refund. In some examples, a type or amount of data transmitted to be used in determining the decision may be controlled by the device. Further, user input associated with requests to override the refund decision may be continuously monitored. A determination may be made as to whether a number of occurrences of overrides for a particular user, customer, or account, has met a first threshold. If so, one or more parameters of the system may be dynamically modified and a user interface reflecting the modified parameters may be dynamically modified. Additional determinations may also be made and dynamic modifications may be performed.
