I have to let you go...

So this morning I get a call from cell c offering me some emergency contact thing, the guy just kept going on without me saying anything except hello.. So eventually I had to tell him that I wasn't interested,.. now why am I not interested, when I have been a loyal customer to cell c for the past 6 years? Upgrading my contracts every 2 years.. I'll tell you.. The phone that I have now is LTE capable, but no once in the last year and a half that I have it, have I had '4g' unless I was in Durban. My network is constantly on no service and calls being ****ty. This has been happening from day 1 of being with cell c. I thought by now things would've been better but I thought wrong, and so I'm due for an upgrade soon and I will not upgrade as I am leaving cell c behind, I have to let you go cell c. I need to join the network my friends have because they always go on on how great their network is..... I'm not sorry.. And I don't thank you for your service
