Disappointed Vodacom Customer

I took a cellphone contract with Vodacom in 2021, I had requested that my old number be migrated to contract which was never done. I later discovered that there is a number that is claimed to be receiving data and airtime which I never received. I have been paying for this contract for the past 24 months, I have been calling Vodacom regarding this issue, and it doesn't seem like they are willing to compensate me in anyway. I pay a lot of money to this company every month, but I do not receive the level of customer care and curtesy that I deserve.
