Heating Sima Installatietechniek

We have been regular customers of Sima for maintenance services. Last week, when our boiler broke down, we called them again and asked for a technician. When we asked, they informed the hourly rate of the technician. The technician arrived, assessed the situation in 10 seconds!, and told us the boiler needed to be replaced. At the end,after a very amateur approach, he charged us nearly double the amount we were quoted over the phone for the hourly rate. When we questioned the charge, his response was simply, "Talk to Sima, pay now!" He took the money and left. The next morning, I contacted Sima, and they confirmed we had been overcharged and promised a reimbursement. Since then, I have repeatedly called and emailed them to inquire about the refund, but I have received nothing but excuses—such as "we lost your account number" and "I haven't seen your email." Despite paying the inflated amount immediately, we still haven't received the reimbursement. For a few hundred euros and due to the unprofessional behavior of the technician, they have now lost a lifelong customer. This is extremely disappointing and unprofessional! We will never work with Sima again! This is a bad example of how you lose your customers!

They asked for 136 euros fora yearly subscription for boiler maintenance (which we paid), then the technician came and charged us 200 euros for the maintenance (which we paid) and he was missing some part so they send us a new quote of 200 extra euros to come back and fix that part they were missing at the time. So we have a total of 536 euros for 1 freaking boiler maintenance? That is absurd

The company reinforces corrupt practices of rental agencies by making tenants pay maintenance bills, which according to the Dutch Law should be paid by landlords. Too bad for them, they lost a good client today.

Had boiler service done by Sima . Extremely friendly and nice service. Would be using Sima for all heating system related work going forward.

After annual check that is always more expensive for some unknown reasons another issue occured 2 weeks later. And you pay full price again to fix the issue. And then they come with administration cost on top of it. Ridiculous
