Migration not processed Ref nr ***

I upgraded on 03/02/2015 to the 24 MTH My MTNChoice 100 mins. On 12/032015 I sent customer services a mail enquiring about the upgrade since the package was unchanged. I received a the following reply: <br> <br> Please be advised that the upgrade was processed but you are still currently on the MTN Anytime 200 TopUp package.Please do send us the copy of contract so that we can migrate you to the correct package.<br> <br> Please do not hesitate to contact us should you require further assistance.<br> <br> Kind Regards,<br> Liam De Bruyn <br> Customer Services<br> MTN SA<br> <br> On the same date I scanned and sent 2 pages with the contract details and signatures to Mr de Bruyn. Nothing has happened since. I mailed MTN again on 19/03/2015 and I also sent an SMS to 44303 enquiring about the status of the migration process Ref no ***. Still no response. <br> I have been an MTN subscriber since 1999 and never before experienced this kind of poor service.
