Out of Bundle Data Rate

I have been a loyal customer with Cell C for 2.5 years. Every month I get an SMS saying I have run out of data and I dial *147# and purchase more data. Last month I increased my package from Smartchat 3GB to Smartchat 8GB. On Friday the 25 September I received 3 consecutive SMS. 1. My current usage is R3523.50 (more than double the highest its ever been) 2. I have 0MB remianing (first time I received warning from Cell C when I had clearly run out many days before that) 3. My service has been suspended. <br> <br> My complaints:<br> 1. This was the first month I never received an SMS from Cell informing me I had run out of data at the time. This resulted in me thinking because I had recently increased my package that I had not run out of data as I had more avail. This is unacceptable from Cell C<br> 2. I have been charged 0.99c per MB out of bundle data rate when my Smartchat package clearly states the out of bundle rate is 0.79c per MB. This needs to be fixed immediately <br> 3. The staff at Norwood were unable to re-activate my line. When after 2hrs this was finally figured out by me paying half my account at Pick n Pay, they didnt know how to upgrade my contract to Infinity<br> Overall I am very unhappy
