No words for lack off service

Waiting for a credit note to be passed since 28 March (for which approval was received) 7 (seven) query references 4 (four) escalation references all advised to me as "resolved" to me via sms. and now 3 (three) months later not resolved yet. MTN' s definition of "Resolved": The SMS we send to the client stating "resolved" does not mean that it is "resolved". It means that it might not be "resolved" because it hasnt been "resolved" yet because it has been transferred to someone else to "resolve" If you want to know if it is "resolved" you must log a query!!!!! Cant speak to a manager, call center cant transfer calls. Only 2 options to speak to a manager 1. Hold on maybe for hours or 2. Leave a message. Problem with option 2 is: 1)customer that holds on gets preference, 2)message does not get relayed 3) promise is made to have manager phone back within 1 (one) hour. 4) promise is not kept. 5) ALL senior management now in a meeting for going onto 4 hours! Please advise if I am know being unreasonable?
