MTN's HORRIBLE SERVICE!!!!1

Good day

Your MTN online people called me to offer me an Iphone XR with data simcard. They **** and said I will get a sim card first then the phone will follow the following week. So the sim card was delivered on the 29th February 2024 and I waited for a phone which never came. On the Ts and Cs over the phone that girl **** and said if I'm not happy with the product I can return it in store within 10 days. So I called on the 2nd of March the whole day your agents been sending me from pillar to post until I ran out of airtime because obviously I don't have mtn I was calling with my Vodacom sim. I called again the 3rd of March your agents saying they are transferring me to someone until they finally dropped me. I called the whole day using my work phone no one is willing to help me return this sim card. Today the 10th March I went to Promenade mall store to return this nonsense sim card they are saying I must call mondo online they will help on their side there's nothing they can do. I want to know who can and will help me return this sim card as I no longer want anything to do with your network, you have a horrible service and do not want to do your job. You are lazy and selfish. I sent emails to MTN customer service, mtn complaints, facebook page and messenger, instagram inbox and Mondo,no one is willing to assist me. Mondo told me that it's not their issue it's MTN's issue. Mtn has been saying they will give me feedback since the 3rd March 2024, no one gave me any feedback, instead they are damaging my credit score!!! Yhooo I despise MTN so bad I even hate the color yellow!!
