online upgrade real dissapointment

So I've done a online upgrade which has supposedly "no admin fee"," no upgrade fee " ; free delivery. All lies I've been charged with so many fees including a upgrade fee , haven't received any of my top up airtime and being charged for 2 devices. My original monthly fee should only be R259 as i specifically choose that contract yet my statements are always above R350 -R500. What a disappointment cant get any help from customer services as they only tell me what I already know. Cant even provide reference numbers for all the calls I've made. Don't ever upgrade online, I WILL NEVER RECOMMEND VODACOM. Cant wait for this contract to end.
