HAD ENOUGH VODACOM!

I went into Vodacom Greenstone intending to upgrade my phone to the iPhone 6, the sales guys told me I couldn't get old technology and I must go for the Huawei P20 lite, I didn't want to but eventually they convinced me. I specifically asked the sales guy if you get ads popping up on this phone as I had it with my work Samsung and it's something I can't handle and never had with Apple. He assured me I would not have this problem at all! I now sit with ads popping up constantly, video ads playing with sound pop up all the time, some I have to wait 5 seconds to close, I am getting directions in GPS and the ads come on and I have to close 4 or 5 ads by which time I've missed my turn off - I can't handle this phone and I went in to Vodacom Greenstone for the second time on Friday - sat there for 2 hours and still the technical guys could not solve my problem. I then get told to come in on sat with a usb stick and they'll download my data and do a hard reset - to which I said no I am tired of being inconvenienced by Vodacom with a phone I never wanted in the first place that was pushed on me. I told them I don't want this phone and they need to make a plan as I had been in twice with this problem and wasted my valuable time and still no one could fix it - I am NOT going through another session where they do a reset and I still have the problem - I have WASTED enough time and I want the phone I originally asked for as with I Phone I don't have these issues. The manager of the store kept running away into the back room as he did not want to deal with or solve my problem, then comes out and says we will have to send the phone in for a while to be looked at... NO Vodacom NO! Then I sit without a phone because I was not sold what I wanted in the first place, now I must waste my time and be inconvenienced more and more - I refuse! I want my iPhone 6 and that is that! I HAVE HAD ENOUGH VODACOM!!! I have had endless hassles with this upgrade and I have reached the bitter end of my patience with you guys!
