Unable to buy data bundles

When trying to buy 1gb night data for R12.50 the letters yy appears on screen, and purchase won't go through.<br> I tried calling, everytime someone who can barely even speak English answers.<br> When I ask to be helped in Afrikaans they say they will put me through.<br> Then a recording plays, asking me my language.<br> After selecting Afrikaans call gets ended.<br> Keeps going in circles like that.<br> I'd recommend staying away from Cellc, terrible service and network, always having issues.
