Rien internet service provider

This internet service provider is the worst ever. The aftersales service is non existing. I have not had a signal for more than 3 weeks and I have received no assistance regarding this. I have phoned and still no assistance. i have asked if I need to buy a booster and still nothing. I have spoken to plenty of people and they all say the same, move to another provider as the service is the worst ever!! Do not waste your money on Rein internet!!!
