MTN Poor Technical Support

Upgrade current contract in Oct'22- data bundle to 60Gb Day and 60Gb Night through Mondo who is a preferred supplier by MTN. I only received 40Gb Day and 40Gb Night data. Logged a case, and won the case, but MTN never called me back to upload the other data on my profile to use monthly. Case number RCO372059. No contact number for the Technical Department to assist with my concern. Have to wait for MTN to call you back.
