Tarne ja tagastused

1. Tavaline kohaletoimetamine järgmisel tööpäeval (Madalmaad). Teistesse riikidesse võib kohaletoimetamine võtta kauem aega – mõnikord tuleb tellimuse kättesaamist veidi kauem oodata, kuid see on alati seda väärt!
2. Tagastamine: saatke meile e-kiri või helistage, et saada oma RMA-number. Ilma RMA-numbrita ei saa me raha tagasi maksta.

Dear All,

I’m Nalaka from Sri Lanka, and I want to express my sincere gratitude for the incredible support we received during an emergency repair of our convection baking oven blower.

Despite the urgency and the weekend timing, your team went above and beyond by dispatching the necessary parts from the Netherlands on Friday evening — even before payment was processed. Thanks to your swift action, we received the parts by Tuesday and were able to complete the repair that same evening.

This level of service is truly exceptional, and I’m deeply appreciative of your professionalism, trust, and commitment. You helped us avoid significant downtime, and for that, we are genuinely thankful.

Warm regards, Nalaka
