No response from the legal department

<br> My account was deactivated and the MTN Attorney's send a letter of demand and l paid the account on the 30th of March and l emailed the proof of payment to the attorney's and they confirmed that they had received it and told me to wait for 7 days for the re activation of my account. After 7 days l phoned MTN and they told me that the case was still not closed and l had to email the legal team of which l did and no one responded. I phoned them on a daily basis and l have to hold for more than 30 minutes and up to now nothing has been done as they are still telling me that the case is still open. Can someone please assist on this.
