MTN is full of ****s

I'm not a happy client who was offered 2 contract devices and when I had a complaint about that contract MTN staff said the is absolutely nothing they can do I took the contract and I just need to move on with my life or add more lines of I have specific needs on a device which are not catered on this one they offered... I just wanted a simple thing since I'm working on my phone in most cases... The phone they offered doesn't have Google services to start with and I bought two for myself and my wife so that we can both use these devices for specific reasons. My wife can't use the udemy App on that device I can't use Microsoft teams on this device let alone that the device decides to freeze at times and one Sim card is not active and I will be charged for serive however the Sim is not active my concept was simple since I don't want to add/take more contracts due to budget constraints I requested for the devices to be changed for different devices With Google services I was sent from Protea Glen mall to Southgate mall from Southgate mall to Eastgate mall which I still did not get any help... Was was I pushed around if they knew that I wasn't going to be assisted? Why is the Sim not active after 8 days of receiving the device? Why can't I exchange this device which the consultant of MTN did not even explain to me that I will be restricted on Apps?
