Poor Customer service!!!!

I took the first contract phone using my passport as an ID document. The passport expired. When I upgraded the contract, the passport was not updated on their systems to the new one. Fourteen years later, my phone was ******. I blocked the line. Later bought a new line and wanted to seam swap so that i can get access to old number, airtime and data line. Mtn is falling to update ID on my profile, not my fault! Now it is almost a month with no access to my contract line. Meanwhile I have paid up subscriptions and has also paid the fee for a seam swap.... I am greatly aggrieved and disappointed with MTN yet again. If for any reasonl you can not honour your promise, you should at least cancel the contract!
