Draw a customer complaint handling flowchart in Mermaid flowchart TD syntax: log the complaint, decide whether it can be resolved now (if yes resolve and reply), otherwise hand it to the responsible team to investigate the cause, propose a solution and discuss it with the customer; if the customer does not accept go back to proposing a solution, otherwise implement it; both paths record the outcome, then follow up with the customer and close the complaint. Use rounded nodes for start and end. Output only the mermaid code block.
