Rain sim swap

I lost my phone in December 2024 and my phone happen to have my rain SIM card in it , within few days after the incident I went to their website to try getting a sim swap or SIM card replacement I followed all the instructions given to me on there, however, Rain never delivered my SIM card in fact they never communicated with me or whatsoever I called Rain countless times trying to find out what is happening , the consultants kept sending me from pillar to post without any resolution to my issue the whole of January 2025, I then decided to cancel because I was not getting the service and shop next door . To my surprise 25th of January 2025 I got sms, emails, WhatsApp from rain saying that I missed my payment , They then started calling me about the missed payment I told the lady the whole story as usually they gave me empty promises saying they will deliver the new SIM card which they never did when I was trying to cancel on the website they said a consultant will get back to me which they never did. Today I got a call from them saying my rain account is owing (>R1k ) for What ?because I have not been using Rain services since Jan 2025 I cannot pay for the service I never received. I am not happy with Rain I do not recommend!!!!!
