Poor Customer Service

I have been contacting Rain for over a week to assist with the wi-fi connection. Each time, I am told it is being escalated to the network team, however, no one has connected me, and each time the case is closed. Upon following up on Monday, I was informed that they dispatched a new sim card to an address where no one is during the day, causing a new battle between myself and the courier company. The new SIM card arrived and the same problem persists. I contacted rain again, only to be given attitude and informed it is being escalated. This is absolutely horrific customer service. No care in the world about keeping customers informed and helping them. I still wait for someone to call me or help me fix the issue
