It ridiculous how long it takes to do a sim swap with staff that have an attitude

I have been RMCS since Friday asking for a sim swap that to seems easy because I'm the owner of the sim card and I have all the relevant information but no its a mountain it's Tuesday today still no aim swap and I have been calling them every day asking for assistance in this it mattered not to them that I use this phone number for work perpose and if patients want to call me they can't get a hold of me. No security questions where asked to find out if I'm right full owner I only got a reference number today when I called for the 100th time they don't have a proper complaint center even now I'm stuck with no sim swap and awaiting for them to finally get to me whenever they feel like it . I work with ppl this is not how you deal with a customer at all they won't give me the patients I will lose while waiting for them to just help me
