Bad service delivery

So I have switched over to Cell C almost a year ago for the most part becuase of their competitive prices in terms of data.. However as of probably the last 5 months I have been experiencing poor reception throughout the greater rustenburg area regarding 3G signal. My problem is this that its not that there is not covarage for the most part when i do have 3g I usually have full bars but my phone keeps switching to edge which is less than useless concerning any data usage.<br> In time I found that in every case when I simply reset my network by means of turning airplane mode on and off it works and switches to 3G. But this becomes a problem when i have to do it every 2 minutes.<br> Now i have reported this issue to cell c waterfall mall to which they reffered me to a form that i had to fill in and wait for the call centre to help me.. I have filled this form numorous times over the last 5 months and only once did a aggent contact me at but after a brief greeting the phone cut of and i never heard back.<br> Since then i have gone back again and no help.. I have even bought a new phone to make sure its not the phone. I dont want to have to switch networks again but seems like no other option
