Upgrade declined

I am so ****ed off with VM unbelievable! i have been a year overdue with my upgrade as my current phone was in good condition and did not upgrade at that time. Last week i decided to upgrade and call VM to find out what options they have for me..To my disappointment they declined my upgrade as they dont have deals going for R320 which is the month-to-month package which i am on and not prepare to offer me something else as i am prepared to pay abit more. They mentioned another option of additional handset with a new cell number but because of my credit history it was also declined. I have been a loyal customer for years.. if I could not afford an upgrade i would not be calling in to change my phone!, Have been having problems with my blackberry in the past and felt that i needed to upgrade . if this is their attitude towards their customers, i would gladly take my R320 and go somewhere where they offer good deals for R320 and abit more! I am so furious.. am sitting with a blackberry which i need to keep on fixing should i have problems with it! Really now Virgin Mobile. U decline but u prepared to take my R320 every month!
