Worst Service with no feedback

Currently having the worst service. Placed an order on the 15th of November. Status of the order still says processing. Spoke to customer services, they confirmed that they received the order and the payment, but cannot confirm why the order is still in processing. Phoned the processing department, they cant even find my order on the system. Tried phoning the processing department again after Customer Services cant help me and the phone just keeps on ringing. Phoned 5 times and stayed on the line for 5min and no answer.
