I want refund

I think 2 months already passed and in that 2 months we had only problems with plugin. First you told us it’s compatibility problem with wholesale plugin we used and you told us to buy wholesuite wholesale plugin because your plugin is compatible with that other wholesale plugin.
Later on after we payed for new wholesale plugin it still didn’t fix problem and after that you told us that your plugin is compatible only with free version of wholesale plugin, after we spent more money for that other wholesale plugin. I want refund because your plugin doesn’t suit our needs.
