I lost wallet address and instead of Luno helping me recovering it, they end up wiping my remaining investment and put me wrong user information which i was not able to access my coins.
I'm pretty sure you've got scammed by a fake support account here, isn't it?
How did you contact Luno to help you recover your funds?
In another occasions, I was trading quietly on Hantec when I decides to involved myself with their investment platform where they offers me a lot of interest, I was so excited that it was keep coming, so I summoned mind to increase my investment on bitcoins with them, I put both my capital and all the interest I have earned from them, then after a while an issues system glitch came onboard, from that I was able to access my account, before I could realized the site is shut down.
There was no system glitch.
The scammers saw that you weren't going to deposit more money for your fake gains that never existed, other people weren't depositing either and so they decided to shut down that site and open another one to lure more victims.
I think you are not using trusted platform on your trades. I never heard about an exchange name Hantec. Where do you get this kind of exchange and are you not familiar on Binance?
I suppose it's Hantec Markets, it's a FCA licensed fx broker, but I wonder if OP used them and not a clone, or someone impersonating them, it wouldn't be the first time:
