Reactie van het bedrijf

Hi Ramesh, Thank you for your feedback. PostNL states that they tried to deliver it on the 18th of November, but it seems nobody was home at the time. Now there is a serious delay in delivering again (or sending it back to us), so please check on Thursday November 30th if it can be delivered. If not, please send a message to our customer service, so we can try to reship your order. Sorry for the inconvenience and this situation will be solved for sure. Greets, The Professor 🙂

Reactie van het bedrijf

Hi Jan, Thank you for your feedback. Good to hear your positive experience, and we are always curious regarding lesser positive lab-results. You can always send our customer service a message to service@professor.nl. We always reply and take every feedback and every message seriously. Perhaps your message didn't come through properly or wasn't send to our customer service. If our RC's were no good, it would've shown in the 1400+ independent positive reviews. Please let us know because we are here to help so we can sort this out. Much appreciated. Greets, The Professor 🙂
