Refusal of refund

Refusal of refund-followup. It is a clear signs of mismanagement and manipulations to find myself having to go back and forth. Consumer friend in collaboration with RCS do this deliberately. The payment was received in their books in December 2023. The additional amount was not queried and accounts closed. The process governing surplus accounts and shortages does not support this business action. I lodged this three weeks ago and the inadequate response is not appreciated and bears no business reasons. So this means RCS and consumer friends pockets clients surplusses where they exists. However where one owes them even a cent all funds must be collected. Professional businesses will provide adequate time frames not idafinate period using words like investigation as if this rocket science. The problem with consumer friends and RCS is that they do as they please forgetting that the people that they assist or offer services to in certain instances have experience around this processes and therefore their spitefullness doesn't go unnoticed.
