Bad service MTN Wellington and Marco

I'm so disappointed with MTN Wellington, I took out two contracts for my mother and father on 18 Dec 2020, 240 min(120 any network and 120 mtn-mtn) and 1Gig dada(500mb social and 500mb anytime) everything was happy, migrated my parents from Cell C to MTN as I have been with MTN since 2006 and always happy with the service. What happened was that the new full data minutesetc was supposed to be loaded on 12 January 2021, to my shock I realised that they didn't get any minutes any a few data. I specifically asked for the minutes as my parents needs minutes as they have uncapped wifi at home. They said yes its the contract with the minutes. When I phoned them to ask, they realised that they gave me the mega s data plan, which I didn't ask for. I went to MTN Wellington and they phoned their manager Marco sitting in Paarl to assist with the fix, he asked if the contact is the same amount and they confirmed yes, he said that the migration will take place soon. To date nothing happened, no migration, they are still on the data contract for data they do not even use. When will this take place. I've made numerous phone calls to both MTN Wellington and Marco, still nothing. This is seriously BAD service. They were so eager for us to take out the additional contracts, but not so eager to fix their mistake.
