How to reply to the customer's email feedback about sales and opinions?

Fu You, I shipped a single bulk cargo to Nigeria last year, which is the first time for the company to export to the Nigerian market. Today, the customer sent the following email about sales feedback: Thank you for your letter. It seems that you didn't understand my email. I said the price here is low, and it can't compare with them. Others. The problem is that we have no colors to choose from, not that we want a color table. If we have all kinds of colors, it will be easy to use different colors in the order. You should know that the price you gave us is too high, which is why it is impossible to sell. We used this to try your products in our market, but you didn't realize our efforts. I sent him some color cards and samples of different colors for marketing promotion, asked him what the price of the products in the local market was, and promised to give him a discount next time. But in the end, these are not helpful to the current sales of his products. What is needed now is how to help him sell his products. I want to ask him about the price of local products, his advertising method and the way to find customers. I don't know if these are suitable. Do you have any suggestions for Fu You? Really hope to get help, thank you! !
