I paid but still no internet for more than a week

On the 26th of January after making a payment for my service I didn't have connection, I called them for days without getting the problem solved. They started suggesting a simswap to me which I did not agreeing to at first because my simcard had a network connection just didn't have internet connection, later on Sunday I was advised to put my simcard on the phone and check if it has network connection just for me to find that the simcard had no connection anymore, to me that seemed like someone from Rain switched off my simcard to bully me into requesting the simswap they have been telling me to do. I was left with no choice but to request the simswap online, and the message I got was that it's gonna take 3 to 5 working days, I called them earlier today to make a follow up and now I was told that there's no simswap request that was made on my simcard because the "shortcode" they have on the system doesn't match the one on my simcard, how is that even possible if I have been using this simcard for years? I use internet for work,now it's a whole week without internet. This simswap thing I was forced to do it and now they can't even deliver it? Every problem they can't fix they tell customers to do a simswap, what's that exactly?

Honestly I am drained, this Rain people simply don't care, that's it.
