No service delivery

I have been trying to convert a number from contract to prepaid from 1June 2015, still with no luck. A process that is suppose to take 24hours. MTN head office being on strike should not be an excuse for everything. Took in all documents on the 1st, they were not copy with the one ID copy, so I went in on the 2nd with another copy which they accepted. I got a phone call on the 15th June, 2 weeks later to say the ID is still not right. I emailed the required document to them on the Tuesday and asked that they called to confirm receipt. No call. Called and spoke to the manager, Mariette on the 23rd and she promised to follow up and feedback. Nothing. Call the 24th and she apologies as she had forgotten. I held while the other employee confirmed reciept of the email and then told me she hadn't even submitted the request yet. When I asked the Mariette about it, she just sighed and said she doesn't know, this is the first she is hearing if this. This is totally unacceptable. Firstly employees service is shocking, secondly the manager should be managing her employees and should have a better response to a disgrunttled customer than to sigh!
