Disappointing service!

So disappointed at the restrictions of changing my spend limit on my sim number and neither the call centre can even help! So, I’ve been trying to change my numbers spend limit on App Stores, specifically the Apple App Store when I tried through a USSD it gives me an error and redirects me to the call centre. MTN could not assist, fairly so because I have contract with Foschini group but how disappointing that even the people who are expected to have full access to my account cannot assist me!

Jaime dismissed me from the beginning telling me how Apple App Stores or any other store is a 3rd party and cannot assist me with changing limit and even goes further on how not even MTN can assist me with this! Exactly how is my own spending limit on my own number a third party thing? It’s my number, limits should be adjustable per my preference like any other network (contract or not) and you guys are telling me you cannot assist? She said they cannot assist nor MTN can assist but she goes on to log a case/ticket with MTN to find out if they can assist! This is just poor service on just general usage!
