Poor Service from Rain

I recently upgraded my Rain 5G subscription to a Rain One subscription. I was sent to additional SIM cards that entitle me to an additional 2G data and 60 free minutes per sim card. It has been about three weeks since receiving the two SIM cards however they just do not work. I do not have access to the internet when using the SIM card not can I make or receive phone calls. I called the call centre twice and both agents that I Spoke to told me to try two separate things which did not work. I Called the call centre the third time asking the agent Mandilake to transfer me to agent Linda who I spoke to previously, but he failed to locate her. He also indicated to me that there were no notes by agent Linda that was on my profile so there was no evidence of what we discussed. I then asked agent Mandilake to speak to the call centre manager who could also not be found at the time. I then requested that he asks the call centre manager to call me once he could be located and unfortunately nobody called back. None of the agents I spoke to even bothered to give me a reference number for my calls.Being a rain customer is becoming a frustrating experience and I just feel like cancelling my entire month to month subscription.
