Double Contract

I recently took out a contract with cell c because I only needed the device and not the benefits as I have another contract. I basically needed only the device plan. Went to cell c mall of the north, they assisted me with the contract mid April, and I was told that they can only cancel benefits from old contract and in turn I will pay for the device only for my old contract. With the new number, I was told that they will migrate the benefits to the old number on the 29th of April 2021. On the 30th of April I called the store to alert them about the migration of benefitd to the new number which they promised they will do. On the 2nd of May I noticed that benefits were actually in the new number and not the old one, I called the store to notify them about the issue and I was told to come to store to sort it out

Today I am in store trying to resolve the issue and I am told that I will have to make a payment of R550 to be able to migrate benefits from New number to the new one. The manager was so rude and told me that it was not possible to switch benefits from the new contract to the old one until the consultant, who was very helpful and patient by the way , called the call center.

I don't understand why I should be liable for payments whilst I was never told about this from the the beginning of the contract. Cell C mall of the north is all about sales and not customer service. I refuse to be ****** like this, I have had my contract with cell c for more than 7 years now and I have never had a horrible service like this one before
