Issue with client.

[abascharles]

Hello,On a contract I'm working on, the client requested for a multivendor e-commerce website to be built with WordPress + Woocommerce, we've been working on this and I've been delivering effectively, but recently while creating the category page, he demanded that a feature "Filter By Search" be made an input field and not a scroll bar, to achieve this I need to purchase a paid woo-commerce extension "Woocommerce product search", I've explained this to him but he doesn't seem to understand, He's always telling me he doesn't care and i must get it fixed, Do I make this purchase with my own funds or do I request for a new milestone?He even asked me to start all over again with manual coding this time, after I've worked on a lot of functionality and spent time and resources already,I explained to him that I've spent a lot of time already working on the project on wordpress and he said he doesn't care.Please I need advice on how to handle this, I'm new here, don't want a bad reputation.
