Cell C 6 Months 50GB Data Bundle

I bought R500 airtime on 15/09 to purchase the 6 month 50GB data, trying to buy the data on 20/09, I received a message from Cell C request could not be processed. Phoning Cell C this morning, I was told that because I did not buy the 50GB bundle immediately, the R500 was used for internet access over 4 days as I’m an excessive internet user and that I should activate the out of bundle limit to 0. When I asked for a reference number the operator told me she cannot give me one as the query is not escalated, told her to escalate in order to get a reference number, she then asked me to escalate what? This is the 1st time I was made aware of this, is this Cell C’s integrity and values by *****ing the consumer and clients money if they do not buy a bundle immediately? So disappointed in Cell C after a loyal customer for 3 years, will look at an alternative cell phone provider who live by their values and integrity. DISAPPOINTED LOYAL CLIENT!
