Allpoint ATM Cardtronics. Allpoint atmin ATM machine did not give all my money. Called and was hung up on. Bethesda Maryland

On november 7th 2017 i went to an allpont ATM. I was withdrawing 300.00 dollars off my card. As the transaction was complete i got my money and it felt light. (The area i was in is not a good place .) so i was thinking i need to count this it felt as if it wasnt 300.00. As i checked back threw my day i was shorted 60.00 dollars. So on november 14th 2017 i went to that same ATM and pulled 300.00 off. As my transaction was complete i grab my money and this time i counted it because i thought about last week and it felt light. And as i thought it was short 80.00. The machine only gave me 220.00. So i run into kroger i told the cashier what happened i was freaking out. And she tells me that it happened to her too. And she said call the number on the ATM So i do so. Well a man answers the phone i try to explain my situation. This man was so very very rude to me and did not listen and cut me off then hung up on me as if i did something wrong here..So i call my card holder to see what i need to do to get my money back..(as my rent is due today.. ) my card holder customer service transfers me to the claims department they inform me its going to take 40 days to get my money back?? So she explains that Allpoint has to check the ATM and they only check them every 45 days. So i call Allpoint back and they hang up on me again so a total of 3 times they hung up on me for what reason? Something dont seem right about that. So i talk to some people i know and i find out that this ATM does this a lot. 5 people has had this happen to them at the same one in the past week and they all were also hung up on when they called. The location of the ATM is 4445 E. 10th st. Indpls. In. 46201. This place is so messed up . why they can just not give the right money to you and hang up on you like owell. What if that happened to them. Thats dealing with peoples lives. Bills, kids, food, ext.
