Terrible service! Both on 135 AND in 2 different stores!

Terrible customer service! I was called several times to renew my contract. When my "upgrade" arrived, I found out that the Samsung S22 is worse than the s20! No micro SD, smaller screen, worse battery. I tried to call MTN to return this abomination of a flagship phone. After 2 hours and being sent to voice-mail I finally got told to drive to the nearest MTN store. When I got there, I was treated very rudely by an employee who was on her phone and made me feel like I was bothering her. She was asking ridiculous questions like who sent me. Seriously ***? Eventually after answering "customer care" to every question, she said, "Oh we don't do that here" and directed me to another store about 20km away. When I got to the next store, I waited for over 2 hours to be served. 2 out of 6 desks had employees serving customers. Several customers left and I heard many complaints and ridiculous excuses from MTN employees. Not everybody can spend a whole day trying to return a phone! This is terrible, inefficient service. I am canceling my upgrade and if I am not contacted by MTN with a satisfactory follow up to this, I will be contacting Vodacom to change over to them purely based on their customer service!
