I was scammed by Bitcoin code (universal markets Steve Mc Day)

My name is Sizakele from Johannesburg I saw an internet advert from my phone more than once aboy a woman from cape town saying that she's making a lot of money with bitcoin code and she's empowering woman to also make money, she also said that she was retrenched n thought that she'll be devastated without a job until she found Bitcoin code then there was form where you fill your information if you interested then I thought of my my son who has a syndrome and I saw àn opportunity for me n him and I registered then they called and they said they calling me in order they can help me to activate my account and they said I need to make a minimum deposit of 250$and i took my husband's salary thinking that I double it in no time as I also saw their happy clients saying that they making lot of money with Bitcoin code and then they asked for my card details and made n Internet transaction and it deducted R3124 in south African rands, then the guy called Teddy told me that an account manager will call me n gave a security code saying that I shouldn't give it to someone else n told me that the account manager will call me within 24hrs and within a minute they called and asked me if I can't deposit more because it will be difficult for me to start trading and make more money with so little money and I told him that I don't have more and he said that he'll find somebody Else who'll bey account manager then no one called after that. I tried emailing them asking them to refund me because no is calling me as they promised. I even replied to this Steve Mc Day who sent me an email to welcome me but no one is responding anymore. Please help me hello Peter to get my money back.
