Very bad service

I called vodacom to do a Sim swap for a number I was using for more than 10 years they told me that they won't help me because my number now belongs to a company called blue label,I am surprised coz I gave vodacom my contact details and now they are telling me that they don't have my details are with this company its for the first time I heard about this company, I don't even know about this thing coz that company don't have my information if they have my information they should have deduct my money in my bank, and now how can I call a company that I do not know and give them my details, it's been long reporting for this matter but without help, now my Sim card is damaged I'm unable to use it, I am a loyal customer to vodacom
