Contract Phone

In October 2013 i purchased a contract phone with MTN detailing that they need to make monthly debits that they did not do they later referred me to ther lawyers for payments i then paid the full amount that was invoiced by the lawyers and now they are billing saying that the account was re-activated in October this without them having explained that the full amount paid to their lawyers was not the full term amount of the contract . I feel the service provider is not very good in providing service to their customers and very disappointed with them
