Bad customer service. Supplied the incorrect material. The mistake was not the issue, it's the fact that their attitude was not to make any discount or to deliver the correct product absolving any responsibility for their error, and hence costing me two visits to obtain the correct product. I went to Another company in the end, whom are cheaper, and included in their price is no charge delivery anyway. This other company have made a mistake with delivery which is fine, especially when they were quite  happy to deliver the correct product, not at my expence. I will never buy from WR Engineering again. Very happy with the alternative company.
