[Conclusion: I did get my coins but it took about total of 3 days 
to get since the volume of support tickets and covid19 situation where most are working at home, but from this small experience I feel they lack on the customer service side.. just as this "manager" admits not having a live option to chat or phone number which seems a common thing which is horrible in the crypto community when running exchange.

Nothing justifies that. I would stay away from coinmama in the future.
3. Changelly - similar to Binance US i go through the process of paying USD to BTC or altcoin and changelly will provide your best options, but in this situation one of the third party they list their website "MoonPay" after verification their exchange on start this process reads as "error can not load" so another technical issue on the website itself.
Changelly is problematic as well, I would stay away.
Changelly used to be a swap service like Instaswap, Coinswap, Shapeshift, easyrabbit, etc... it used to work well, but they started to demand KYC to make those swaps, then there were some scam accusations about them on the forum..
