“Whistl Parcels' proactive approach has improved our delivery performance, marketplace seller status and customer feedback. It has taken a lot of weight off our customer services team, who now spend less time trying to find parcels and more time focusing on running the business.”
“Whistl Parcels' proactive nature enhances our customers’ delivery experience and has taken the pressure off our staff, thanks to their innovative SMART Notifications platform, which identifies sequences of scan events such as bad addresses and then generates a ticket for Whistl Parcels' customer service team to rectify potential issues before they become a real problem. Ensuring our customers’ expectations are at least met and often exceeded has been instrumental in us achieving 100% positive feedback on our eBay store.”
“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. ”
