MTN Technicians not loading correct Data Bundle.

Good day I've upgrade my MTN contract via Mondo in October 2022 and is still waiting for MTN to upload the correct data bundle to my profile. Query RCO-372059 was logged explaining that an 60Gb Day and 60Gb Night package was offered from which only 40Gb was loaded. According to the sales representative the sale was investigated and found to be in my favor, hence nothing is loaded unto my account. After various calls to Mondo and MTN I'm still waiting for MTN Technicians to call me back to upload the data bundle to my account. There is no contact number to follow up. I have another contract due to be upgraded, but waiting for MTN to solve my issue pending for 7 months now.
