Unwanted subscription and XtraTime

Dear MTN

This morning I just received a message that my XtimeTime balance due is R5.50. I have never subscribed to the service and I am not interested in loaning airtime. Please remove this thing urgently on my account. One more thing MTN keeps sending pop up messages to many subscriptions and I always opt out but those messages don't stop. I have been a reliable customer to MTN for over 15 years and for the first time this year I am disgusted by these many subscriptions. If i want to call I will buy airtime like wise with data. Please remove it asap
