BAD SERVICE

I have an airtime problem where I cannot see 2 numbers , called the call center held on for 30 min yesterday , today I decided to speak to a consultant via the chat onlt to be advised that I need to mms the voucher which will cost me 50c I advised consultant that I dont have airtime and they said that is the only way to be assisted

did another chat and consaltent Danilli Fransman told me to return the airtime where a bought it , asked him if there was another way or can i fax the voucher and there was no response.
