Query: NOT WORKING PROPERLY

Bought this product after reading the reviews. Got the items on time and installed it right away. No problem as easy as 123. We left the house by 6pm with nobody but the activated minialarm plus. after 30 minutes, the alarm contacted my cellphone number as per programmed. so I called back my house number/system (per user manual) to acknowledge that I got the alarm and turn off the auto contact, but Its a failure. every 15 minutes minialarm will call my cellphone. finally we got home at around 9pm, worrying that somebody could have entered the house. fortunately, nothing was missing. I tried to reconfigure the alarm but still it keeps on contacting that programmed number. per user manual, you can deactivate the auto dial by calling the number but i can't deactivate it. So I ended up returning the product before lossing my hair on my head.
