Disappointing Service

I cancelled my 4G service on the 14 June 2024 and received an email saying my request has been sent the escalation team. However, Rain cellular did not cancel the 4G service. Now, my 5G service has been suspended on the basis that I owe Rain cellular. I am expected to pay for July and August for a service I canceled in June. 2ndly, I requested for a replacement 5G Sim card and explained I was in Europe. I was advised to scan my ID and send an authorisation letter to my nephew who would then receive my Sim card but CCD couriers refused to hand over my Sim card. I have been paying for the 5G service but my service has been suspended. This is not fair and is totally unprofessional by rain. Calling in is a waste of time cos it's either you get cut off or Noone can help. Sending an email to support is utterly useless cos the reply is automated saying the email is unattended. I am fed up and frustrated. I am using this medium to find answers otherwise I will look for another service provider. Rain cellular has disappointed me.
