CELL C billing problems and pathetic survey

I at 08:03 receive SMS from Cell C saying that my account is overdue . Please pay urgently or call 084135 to make arrangements. Called Cell C but failed security test as I didn't know what type of credit card I have (I rep**** Sanlam Money Saver, Blue, Platinum) but alas I failed. Called back a second time, went through security test process and passed (different easy to understand questions this time) just to be advised that my account is up to date and Cell C have a problem and other people have also called in for non-payment only to be told account is up to date. Then the cherry on top, I get invited to answer a survey rating service (1-5 with 1 lowest) Their survey system doesn't recognize 1 nor 2 - obviously they don't want bad results from the survey. I have better things to do then waste my time sorting out their problems
