The best thing you can do is not to relent in giving him all the support you think you can offer him. Take note that we have individual differences and our views are different. So regard his rating as his own view, don't try to take it up with him....ignore it and continue to provide him quality support. In doing that, do not try to convince him by doing more than what you can afford.keep up your good work, that's all I can say.
