Netstar don't go there

Very very bad experience. I signed up and the product was not delivered as advertised. Had to pay extra for wireless remote on top package as well. Once installed started to get false alarms while sitting next to car. App only works on specific devices not for Huawie. Wanted to cancel imidiate after installation as it was not delivered according to contract. I had to pay R3500 for not using the product to cancel the agreement. What happened to 7 day cool down period?
