Bad service

day

I am writing this with a heavy heart. I went to Vodacom on Saturday the 27th November. I wanted to buy a nova 8i and the consultant told me that is doesn’t have play store and told me about OPPO phone. I told her that I’m an iPhone person and I need a phone that has more or less the same features as an iPhone. She assured me that the OPPO phone is the best and all of those things. When I got home I found out that it’s nothing like I had imagined. First of all it over heats when charging and I can’t use the phone while it’s on charger 😒😒😒, t contacted vodacom in mall of Africa and asked for either a refund or an exchange and I was told that I can’t as the box is already open, is this how it’s works? I want my money back or another phone as this one is just ******* and I can’t use this phone. I paid R7100 for a useless phone😡😡😡😡. Please assist me with this as I have only two days left for the 7 days thing to end

My numbers are ***
