Hello Mr Ward,

Thank you for leaving us a 5-star review. We are happy to hear that Francesca provided great service. Your query is currently being reviewed by the wholesaler. As part of the process, we are dependent on their investigation and response, which means the case may take longer to resolve than our standard timescales. We appreciate your patience and will keep you informed of any updates.
