BitStarz complaint: 70 mbtc denied on cashout

I deposited several thousand dollars playing with bitstarz casino prior to my bad experience with them never encountered any problem when cashing out any winnings however I experienced a period rather longer than others with no luck so my account had many deposits to the account but no withdrawals. Then I made a small deposit of around 20.00 USD and won over 70 mbtc equivalent to around 2100.00 USD . Given my recent no win streak this was very exciting so I tried to withdrawal my winnings but was told my request was denied due to a previous deposit from a month and a half prior to this incident no being ed on the Blockchain . When I spoke with customer service they kept saying I needed to expedite my fee for the sending platform however they of all people should know after 24 hrs you are unable to make adjustments to your transaction . My disagreement with the casino is they still allowed me to deposit a significant amount of money and play through thinking I was able to cashout if I would win. The deposit that effected my withdrawal was many deposits before the one I had one using the funds from . Ultimately I played out the 70 mbtc as play money since I my efforts at resolving the issue with bitstarz turned up unsuccessful. I feel I am still entitled to the winnings I tried withdrawing with them since I didn’t play out any of the balance until after days of no answers or help from casino customer service .
