MTN pathetic service

Hi, I went to the MTN Cornubia branch to migrate my contract to prepaid on 9 March 2019 as the contract expires on 27 March 2019 and was told to call the call center on or after that day and they will migrate it as there is no notice period, if they cancelled it, it will be immediately cancelled and I will lose my data and airtime.

When I called the call centre just now, they told me that there is a 20 day notice period and that I cannot cancel today as it is not business hours. They also told me that this mtn rule was standing since 1 March.

How am I supposed to migrate to prepaid when MTN themselves don't know what to do to migrate, shouldn't your staff know the procedures or is this just a tactic by MTN to prolong the procedure or force the customer to look for another service provider?

I received another mail saying that the migration notice is now 30 days, this is in a space of 30 minutes,

If your staff do not know their work, they should tell us, now I feel that I am being pushed from Pillar to post and do not appreciate this.
