BAD COSTUMER SERVICE

i have a contract phone with MTN contract i have a problem with my Data bundles that are depleting very fast. So last week i decided to call MTN and enquire about my data bundles. i spoke to the agent called Keerath Jagarnph who advised me that I'm receiving less bundles than what I'm suppose to receive. So when i ask him to correct it so that i can get what I'm paying for he advised me that i need to pay R1000 for them to correct and i asked if can i cancel the contract he said i will still have to pay the penalties which i feel its unfair and it a ****************. The error it was not on my side so i don't understand why do i have to pay for the error that MTN made. I then request for the consultant to send me whatever that he was saying in writing , he said they don't have access to email which i find it amazing that how can you be dealing with customers whereas you don't have email address, i also advise the consultant that can he at least ask his team leader to send it to me in writing since he does not have access to email to email. He said he is not allowed to do. So i feel that the consultant was not professional and i didn't get all the help that i need from him because i don't understand when he says he doesn't have access to email and the team leaders are not allowed to send anything in writing. Please listen to the conversation that i had with your consultant, i believe your calls are recorded.. Can you please sort this out and can i kindly have a feedback as soon as possible.The ref number that was given to me *** and please contact me on ***
