Terrible Telkom Service - Waiting from Feb this year for a new phone unit for house

I have been requesting a new house phone from February this year. Telkom changed the landline/house phone in August to now have data as well. Again I have called numerous times to advise that my phone is not compatible. I have been paying this contract and I cannot use all the functions available on the product. Please, Please can I urgently have a new phone that is compatible with your new product.
