“We have a strong working relationship and always work collaboratively to find solutions and improve our customer experience. The team consistently demonstrates a deep understanding of our brand values, enabling them to deliver tailored solutions that align to our vision.”
“The team have always strived to assist us in reaching a resolution. It is refreshing to work with a team that is commercially driven, but who genuinely seem to care about our business and its success. ”
“We would have to employ at least three additional customer service advisers of our own to manage the carriers. That’s a big saving for a business like ours. We really do see Whistl Parcels as an extension of our own business, and we have spent the last three years further integrating and refining the customer service team to create more efficiencies and strengthen our proposition.”
