*** - BIS + Clip Charges on a data contract

On 22 Dec.'15, I queried with Customer Care why I am being charged for BIS on data contract & was advise that it would be cancelled & the charges reversed. In Jan.'16, I receive my statement/invoice & noticed that there is NO charge for BIS but that NO credit has been passed. I then noticed that I am also being charged for Caller line identity on the same data contract. I then call Customer Care today to query the charges & I am asked if I would like to cancel the caller line identity. I then get told that it is my duty to cancel this service on my contract since I requested the service on my previous contract. I then explained that I was sold a data contract on my upgrade & therefore it cannot become my responsibility to cancel the service. Problem is, I didn't change the contract & therefore the person who sold me the product should have ensured that this was done. Who then process all contracts to see that everything is in order or is it all about the money & hope that no-one notices the extra charges. What would I be doing with BIS+Cli on a data contract when the sales person clearly stated that I would not be able to make or receive calls. Now I'm told NO REFUND
