DISGUSTED AND ANGRY

So the response i get from MTN is that 30 gigs of data was used up nd no data lost. 30gigs of data WAS NOT used up!!!! It was taken away at the end of the 30 days!!!! So data was not lost. Don't give me that BS that no data was lost. I did not sign up for 30 gigs as a once off. 10gigs was supposed to be allocated over 3 month. Now I want my other 20gigs that I signed for!!!! Otherwise I will be taking this to my lawyers for breach of contract!!!!!
