Messed up my account

<p>I have been with MTN for the past 4 years and i have been opaying my account via eft every month for some odd reason they were removed from my beneficiaerys and i couldnt add them again so i call and set up a debit order for the 31st of every month starting from the 31st of March 2017 i have sent them multiple emails and no response i would like them to cancel the debit order so that i can carry on paying it myself cause they have debited my account after the said date and messed my banking up very poor customer service and i cant understand how hard it is to follow a clear instruction , because it being a big business and all that does not mean they should get away with the **** they do to its customers cause if i dont pay they will add a default to my name but if they mess up what happens NOTHING i wont leave this **** until its sorted out a new month as begun and i want it sorted before the next pay day cancel my debit order and give me feed back </p>
