Account Suspended in Error

Last week my Ipad mobile connection informs me that I am out of data and need to purchase a new bundle, I try via the links given but the MTN website does not allow me to purchase another bundle so I contact the call centre, no problem, I get another 5GB and cough up R430,00. Later on during the day I get the same message and contact, via email a customer services rep, she advises that I actually do have over 7GB available so I should not have purchased the 5GB. Spent the whole weekend without being able to connect and this morning I phone the call centre, I firstly confirm my pin, they confirm over 7GB available, they transfer me to technical, I confirm my pin and go through the whole story again, now I am told my account has been suspended. I get transferred to accounts, confirm my pin, no the same pin that I have confirmed twice is now not valid, answer the 10 questions and get advised that my account is active again as it was suspended in error. Now my questions, on Friday why did the operator not advise me that firstly I still had data and secondly why did she not advise me that my account had been suspended? I now have paid out R430,00 that did not have to nor will I use that data all because MTN is ***********.
