Activate my account

I am trying to get a hold of MTN and their call centre is closed. They deactived my services yesterday without informing me they would. All they told me was i have reached my cap. I made a payment today and now i cannot have my account opened. <br> <br> I do not know what to do or who to call to have my services back up in use. Their self service portal does not allow me to reactivate my services. This is very frustrating as I don't know how long they will be offline to grant customers service.<br> <br> Could someone please call me back to advise what I must do. I urgently need to use my phone this is a huge inconvenience.<br> <br> Very irate customer.<br>
