RUDE DISAPPOINTING CALL CENTRE AGENTS

My husband Ebrahima Roberts called yesterday 08/04/2021. They called him back today this morning just after 8am. The called cut and they didn't bother o call him back. We called now at 15:17pm only to be told that it was declined by someone the agent could not explain what this mean and put me through to loans saying she is from card department when I chose loans on the IVR. She put me through to another agent and she said she couldn't see or bring up his details however the agent in the card division could but he never app**** for card he app**** for a loan. The agentbsge passed me through could not get us a team manager at the point of requesting it. She kept saying 24 to 48 hours turn around time. This is acceptable as there should be a team manager available for customers calls. When I asked the agent the team manager should call us back as this is a expensive call. She kept saying 24 to 48 hours. Is this how you teach your agents to treat customers. This is the first time we dealing with your call centre and with RCS. This is very disappointing to know new customers get treat this way. I want a manager to resolve our query quickly and in a professional manner.
