Beyond unsatisfied customer

Unsatisfied customer This was a complaint that i wrote on the 17 July [on the 17 July I logged a complaint regarding a faulty router that needed to be swapped. The call was logged and the agend did his due diligence accordingly and said within 5 - 7 working days the router will be delivered. Until today I'm still waiting on rain to do the swap. Been logging numerous WhatsApp complaints and the same outcome. And called. Wow nothing. And i have 3 routers with rain a very unsatisfied. Upset indeed customer. I need to cancel my subscription with rain. Well they are willing and very ready to cancel the three subscriptions.] And rain called once and I couldn't answer the call during working hours. They never made contact until today. Still struggling with the same issue. May rain kindly advise. Whether they are going to swap the device or I should consider finding another provider as this service is not rendered for free.
