Uninterested Consultants with No customer service Etiquette. very disappointing

Absolutely Terrible customer service. A consultant phoned me on the 2nd March claiming to be from MTN, I proceeded with the upgrade, the consultant advised that they would call me back... it had been a week with no contact. I phoned MTN and was referred back to Mondo several times, the Mondo call center line is very useless i have been phoning for a week and no one answered my call. Eventually when i did get through to a consultant I was told that the first application would be cancelled and submitted again, another week went by with no feedback, every day I had to phone and ask for assistance, I eventually made use of the lie chat on the Mondo website and every single consultant that I spoke to advised that they cant help me, and that they would escalate and they never did. every single time i requested for help i was told that there are no managers to escalate to, or that there is no way for me to log an escalation, every time i spoke to a consultant they had an attitude like they couldn't be bothered that i have been waiting for my handset for two weeks. a very non-cholent attitude from every Mondo consultant that I spoke to, till this day I am still waiting for an update. I understand that the waiting period is 3 to 5 days, but surely I cannot be held accountable for the fact that my first application was blatantly ignored. I have never been so disappointed in customer service like this before. Mondo made contact with me first and never ever came back to me, I have to waste my time being transferred between MTN and Mondo because no one seems to know what is happen. I find it very ridiculous that I as a customer has to phone every single day for an update that cannot be provided.
