Continued Vodacom promises

On 23 november last Vodacom SMS'd me: " Dear Valued Client. Our Radio Planning team will be in contact with you ...." Nothing has happened. On 31st December I was told that site visits will be conducted after 5th January. Nothing has happened. On 10th January I was told "... we are looking at improving coverage for your area ..." Nothing has happened. All this after I complained about poor reception in the Franschhoek/ Paarl area. My signal is so bad that I have to use my land line for business calls, and people who call me can usually not get through.
