after sale services poor

I bought a phone in this store and after 5 days it gave me problems I took it back and they said its a software issue I must take it to MTN after taking it there it worked for a week then went back to its problems, I continued using it for about 3 weeks then it just froze, when I took it back they told me there is nothing they can do besides taking it and putting it in their stockroom like others coz MTN is on strike, and when I asked the lady then what am I going to do since I am phonelesss she said \buy a new phone plus I'll borrow you my beanie"so I got frustrated and requested their area manager's number and they delayed so much that I ended up searching for their customer service number then I spoke to a lady named Jenny Hawken who told me its not their problem MTN is on strike they just a third party and they are not technicians after a 5 minutes fight over the phone she referred me to a guy named Racy who was first disrespectful coz he is an area manager and I work in the mall and insisted I take the phone for repairs and MTN will pick it up whenever. See me in a TFG store buying again :e"""
