Unfair practice - premature upgrade

I am writing this to air my discontent with requesting an early upgrade. I know nothing will be done and nothing will change the situation but I feel I have to write this. I am due for an upgrade in exactly 4 weeks. Yesterday my old phone fell and is now totally unusable. I can't have it fixed and I'm now left with a dilemma. I'm a single mother and always need to be in contact with my children. I also use my phone for work purposes as I am on standby at times. Now I'm stuck for four weeks because my average spend on the account is not R 1200 or higher. My average spend is just under R 1,000. I am now considering trying to take my account across to Cell C.
