Cell C again!

I am still buying every month 200GB data at Cell C and for every online purchase (R1,699.00) I have requested a proper V.A.T. invoice via their website. Although Cell C prompted on their website to email it (the correct email address was submitted), it was not sent. I have had this issue now a couple of times but they do not seem to see the need to change and automise anything on their online sales processing! Regretably they did not even contact me on my cellphone number as provided. Not good for the reputation of Cell C and even worse for the income of SARS which urgently needs funding to keep our country going!
