Smart geyser... impossible purchase

I don't know when last I dealt with such useless a company. I really want to actually purchase your product, being the smart geyser until. But 5 attempts later to give you my address and you are still trying to send the poor plumber to an address of a car I owned 15 years ago. It seems no one is able to capture an address or your system keeps overriding it. I have 0 faith to sign up for 3 years with a company who has such useless service. I can not express how frustrating it is in dealing with your company. Now I wonder where else I can get this unit from. Because dealing with you is impossible
