Not impress with the service

I am not please with the system. I have received my data SIM card on the 14 October 2022. I have trying to get in touch with Mondo for two reasons one my email address was wrong and the courier never took my proof of address. I am still waiting for my sim card to be active. I received a email on Friday from Mondo to say they have fix my email address I much fix it at Telkom. I spoke to customer care consultant and I was advised that they have got nothing on my name by theme. I have trying again to fine out what's happening but I have to speak to a robot.
