Sim swap frustration due to a non-existing contract

<p>I cannot even begin to express the level of fustration i am feeling, apparently RMCS has "a contract" with me on my prepaid airtime, I dialed the number countless times.</p> <p>I dont understand how these people got my details aI purchased a prepaid sim almost 10 years go. I am not sure what to do and how to proceed as now I have to loose a number. I I do not understand how these people are being paid, and by whom or when and what is the method they receive their payment as I purchase airtime daily. Now I cannot even do something as a simple sim swap. I d really like some help and have not the faintest idea what to do or how to resolve this?</p>
