Bad Rain support services

My phone was ****** end of November 2022 whit my 4G sim, so I hade to do a sim swap when I received the new sim it was not working at all there was no cell service on sim card I and the card was blocked on automatically select network and could not switch on the mobile data as the sim did not support the service, I did insert the sim in a norther phone that uses 4G and it was still not working. I have numerus complaint to rain support they did NOT get back to me as the promised whit there e-mail system. out of 8 times they only contacted me 3 times back and that's was only after spamming messages (tickets) to them to get them to contact me back, Up until 31/01/2023 my sim is still not working and i have been charge full price for 2 month of no rain service, There support system is is the worst as the only offer empty promises. 19/01/2023the lady person promised the get a engineer to contact me I'm still waiting 20/01/2023 the guy promised to get a engineer to contact and a credit for the for the 2 month and I'm still waiting 24/01/2023 the lady that contacted me was unbelievably rude to me.
