bad service

hi-i have a contract with 8ta with an additional 8ta card.for the 1st year we enjoy the benefits of free calls 8ta to 8ta. so this Jan 5th i rec a sms to say if i want this benefit i can keep the benefit was R49 more per month-dial *123# and follow promts- which i did and it didnt work. however i called the call centre who had no clue about this sms- so after explaining they said they cant do if for the next year they will add R49 advance to my contract and i can buy it for JAN- they will check with marketing and get back to me asap- its been almost a full month and nobody has contacted me via call or email.this is very unprofessional.please have a look at this and give me some feedback
