Messing up my excellent ITC,rejecting upgrade for no valid reason

<p>I am due for an upgrade, I have 2 contacts with vodacom, I was on autopage and both my contracts got handed over to vodacom. I had excellent service from autopage, but vodacom is terrible. Called in for an upgrade I apparently do not qualify for an upgrade even thou the phone I want is lower than then amount I'm currently paying, I was not explained the reason as to why I have not qualified for an upgrade properly, I have never missed a single payment with vodacom as I have debit orders every month. As a result I have a feeling that they are messing up my credit ITC rating. I do not want your services anymore, today Vodacom lost a loyal customer due to terrible service. I will be sending in a request to END my contacts and please don't mess me around again! I want to know why don't I qualify for an upgrade and until someone contacts me and explains to me as to why I don't qualify, I will take this up with the credit beurers - I have all records from trans union of every payment made to vodacom from the start of my contracts. Totally dissatisfied customer...please get someone who has ITC knowledge and explain to me why, the customer service call centre is useless and I don't plan to waste my time holding on the phone for an upgrade to be told I don't qualify!</p>
