Rude call centre staff

Cell C continuing to pester me. I missed a phone call from them this morning. I answered this afternoon and indicated that I was not interested in purchasing anything, however, mid-sentence (I was mid-way asking for my contact details to be removed from the system) when your consultant simply cut the call and hung up on me. <br> <br> It is indescribably rude to impose on someone and then have the audacity to hang up on them at the same time. Shame Cell-C, the people you employ epitomize your brand, which is all-in-all is pathetic.
