loyal customer wasted time

<p>I have been a loyal customer with Cell C for a while now. I have 3 contracts and I upgraded one contract last year October. But I was told that I cannot upgrade my other line now due to certain reasons. I have not missed a single payment on any of my lines and have always met my payment obligation. Due to not being able to upgrade I have cancelled my line and have taken up am offer with another network who is more then willing to offer me a deal. I find it hard to believe that I was not accommodated even though I was looking at taking a cheaper offer. </p>
