The quality of the products and customer service from Slims Detailing has been very good. Fast turnaround and exactly as expected. The courier service used however has left little to be desired. Although initially they tried to deliver on time, they offered no option of tracking and communication to for the customer. This resulted in a non-delivery and a note through the door, where I would have been happy to append a tracking tool to acknowledge a leave location to avoid or propose leaving with a neighbour. From the note, I then proceeded to use their website to confirm I would pickup from their depot (big inconvenience and negates the purpose of delivery...) as the offered dates for re-delivery would have been into next week and too late for my needs and also derived he same problem as I couldn’t be at ho e in working hours. Having, made the journey near the end of the working day to the deport, I arrived to find that they had ignored their own system and put the package back into a van during the day to deliver (obviously without success as I was at work). When I asked for support and suggestions on what could be done the only response I had was to wai for the delivery driver to return or book an appointment the following week (as they wouldn’t deliver at weekends, both unacceptable, however I needed the products so wanted and hour and half for the van to return upsetting my evenings plans. Their customer service and communication was extremely poor and lack of ownership and accountability of 5e issue to resolve non-existent. I would thoroughly recommend that Slims Detailing consider using alternative courier services where better flexibility and customer principles are a driver for their business as I would hate for their poor performance to have a lasting impression on your business. My rating reflects the overall performance, however with a quality courier this would have easily been a good or very good rating. Regards Joe
