Misinformation from consultant

Between the 23rd and 24th of April 2021,I enquired about once off data,was told about pro rata for the 6 days due to it being nearly end of the month which was not a problem and I'll be get 75% discounts on the data for my top up contract,the consultant (shelby)who helped said it was recurring and he knew the consultant who helped me should have explained it to me how it works and now I must pay nearly R700 which is out of my budget and I definitely don't want to be credited. That consultant will be receiving his full salary whereas I will be thrown out of my budget,zama logged a service ticket for me which I didn't get the sms for as yet. I need this resolved ASAP even though the bill run has started,not my fault I was misinformed by your people's *********** staff's.
