Poor service from MTN

I recently entered a new contract with MTN during level 5 lockdown having expressly said that I needed my number ported from Vodacom to MTN. The new phone arrived with no SIM card and despite over 10 attempts to either my number ported or at least provide me with a new SIM related to the contract so I can access the benefits for which I am now on the 3rd month of paying we have still had absolutely no resolution! Should no resolution be found within the next week I will simply stop my debit order
