Very unhappy with my new contract recycled cell number

I have a new contract with vodacom (uChoose Flexi 230 plan). After speaking to vodacom customer care a few times regarding my problem, the did nothing and just say that they cant do anything about it.

#problem Since i got my new contract in sept 2019 i get so much calls, sms's, whatsapp's from people looking for a Wisani person. Vodacom informed me that the contract plan that im on (uChoose Flexi 230) comes with a recycled number. Vodacom never informed us about this. I want my number to be changed. Im using the contract but the contract is on my husbands name. My husband is on the road during week days. I will not accept this bad bad service and will not recommend people to go to vodacom. I want a new number ASAP.
