Migration fee charged when contract was upgraded!

I used the MTN UPGRADE CHECK on their website to see when I was due for an upgrade. The date that I was given was 7 March 2021. I then upgraded on 7 March but on the March invoice I was charged a MIGRATION fee of R444.06.

On 30 March I phoned the customer service line to correct it. That same day I received a SMS stating that the case was closed. I phoned again to find out why the case was closed and why I did not receive a refund. The answer I was given was that I was only due for an upgrade in June 2021! I asked the consultant to open a case again because the date on the website said that upgrade was due from 7 March 2021. Shortly after I received a SMS again stating that the case is closed.

Why am I penalized for upgrading on the date that MTN's website upgrade checker gave me? Also, I have received numerous emails thereafter stating that I am due for an upgrade (April 2021). Why would I be mislead again by these emails if my upgrade is only due for June 2021? I have the signed contract/application where “UPGRADE” was marked and it also doesn’t state anything about migration.

I requested a refund of R444.06 as I feel that the fault lies with MTN and that I was and am still being (referring to upgrade emails received) mislead with incorrect dates. I have sent numerous emails requesting feedback with no luck to date. Very disappointed!
