Wi-Fi connection

Good day please kindly assist, I need your help with Rain as a service provider , I purchased a Wi-Fi router on the 2nd of June26, how ever the delived a faulty unit and after a day the came to exchange after giving stories that it need to be changed when the unit doesn't have a battery or so... On the 3rd I call them cause the unit was not activated they said I should wait 24 hours for activation nand days gone by still nothing, I've calling them since the 1st n today is the 9th still nothing, I'm told they still waiting for activation and I'm working from home now I need to buy data separately to work and buy airtime to call them every to listen to the same story they give me every day.. Just feel like I'm being ****med cause they won't put call to anyone dealing with such matters
