Charismatic Doberman review: purchasing a male doberman puppy 1

On 10/23/17 I lost my 12 year old male Doberman. This totally ripped my heart out. I began searching for a Doberman breeder when I located charismatic Doberman in mcalpin, Florida. I submitted an application and followed up the next day with a phone call. I spoke with sue. I explained my situation and she stated she had a liter due 1/17/18 with lady. The price was $1700.00 and this included ear cropping. I made a $300.00 deposit 11/17/17 to reserve a male puppy. 2 weeks, or so before lady was having the pups I received an email from sues husband. They stated they thought lady was going to have a small liter, maybe 4 pups. According to them her last liter was 14 pups. I was crushed as I just wanted a puppy. They offered to transfer my deposit to another liter. After emailing we agreed to wait and see about lady as sue said she could be wrong. On 1/17/18 I received an email stating lady had 2 pups both females. Again I was crushed. After several emails back and forth I requested to have my deposit refunded. The following morning sue called. She stated they were going to breed Greta that week however there were problems previously but they were trying another male. If it took pups would be here end of March or first of April. She also stated she had 2 other liters due about the same time and one of them she only had females available. According to her husband I was second in line for a male. I ultimately told them I'd wait for Greta. Several weeks later I texted sue asking about Greta. She said all was well. I asked her for a date she stated 4/1/18. On Tuesday 3/27/18 I texted sue asking about Greta and was the date still 4/1/18? No response. On Thursday 3/29/18 I emailed in the morning asking the same thing. Her husband responded that evening and said it was a "false pregnancy". I was livid. I emailed and told them to refund my $300.00 deposit ASAP. He responded and said there were no guarantees with Greta and he thought I was waiting for first available. I was told they were uncertain which is why I texted sue asking several weeks later and she said 4/1/18. It's 3 days before and until I asked twice they didn't contact me.
He tells me that they have 2 other females that will be coming into heat and I could wait for that. No, no way. Someone is lieing. Sue said they already have deposits for males on one of the dogs and he's telling me they aren't even in heat. This is outrageous to me.
I sent him an email on Friday, again telling him to refund my $300.00. All he says is when he does he will let me know. Obviously they don't have $300.00 or why wouldn't it be refunded immediately. If this is not refunded by Monday I will go to my bank and have them deal with it.
The fact that they can take peoples money for puppies when they don't even have a pregnant dog is unconscionable. Sue was aware of how upset I am and yet they play with peoples emotions, all for money.
I will get my Doberman puppy but not from this breeder. I thought they were caring, compassionate people, obviously I'm wrong. Unlike them that evidently doesn't have $300.00 I do have the money to buy another puppy. They still show on the web site to make reservations for spring liters. They don't have a spring liter. Someone needs to stop them.
