Staff misbehaving

Manager of California's liberty branch is very rude and does not know how to talk to the customer at all. First they made our bill wrong and later they were not admitting the mistake۔The guy who took our order was admitting that he made a mistake but the manager was still arguing and refusing to refund the money and was fighting. I request you to replace such a manager who does not even know how to talk. Otherwise, we try not to go such a place. Otherwise we will try not to go such a place. But the guy who take our order is a good person and stop manager and repay our money. I made online payment from jazz cash.
