Cell C Flexi bundle recharge takes money but does not load data

I have been working on Homeconnector buying the flexi bundles. Last month I bought 80GB and proceeded to renew for this month.I always buy the data on the Cell C app.The money was deducted form my account but the bundles never loaded onto the browser.Now I am left without both money and data.I have called Call Centre on 135 and noone is giving me any help.I am struggling.
