PAYMENT PLAN KEEPS CHANGING

I was going to study through Damelin as they offer a Payment plan which is what I require financially as I am paying for my own studies. I contacted Damelin and I was sent all the information to make a deposit and then what my monthly payments for 12months would be. When I contacted the rep again a week before I was going to do the deposit I was informed that all of a sudden there is no longer a 12 month payment plan and I will now need to pay the fees over 6 months which I currently cannot afford. When I followed up about this I was told that ONCE AGAIN the payment plan has changed I will be required to pay the full cash amount upfront. So I contacted INTEC which is apparently part of Damelin once again they sent me the 12 month payment plan with deposit fee. A few hours later I get another email saying INTEC have discontinued this course and I must go through Damelin. All these changes within a few hours of me making queries and trying to register with them. Is this how they operate? How are students meant to afford this cash upfront fees and certainly you can't tell a client one thing and then change your mind every few hours. Very disappointed by the service.
