Once you're a customer they could'nt be bothered

i am a cell c customer for around 16 years. i have 4 contracts with them to the value of around R600 per month. i called the call centre to upgrade one of my contracts wanting a certain phone. they give me a story that i can't get that particular phone because its not the same level as the existing contract. what\s the point of calling it a upgrade if they cannot give you something a little better than you had before. they should call it a side grade. anyway the reason they say is that credit vetting has turned down the upgrade from a R149pm phone to a R249pm. my accounts with cellc has been squeaky clean ever since i first subscribed and now all of a sudden they cannot trust me with a R100pm increase in contract. they know that its too much hassle to cancel the contract and move over to a different service provider so as long as they got you in the system they dont have to worry about you any longer. I think its time for a change. there are much better deals out there. I think i will seek one of them out. Starting with this contract that is almost at the end I will move the rest of my business over in time."
