Charged x3 for subscription & email limit imposed after 2 weeks

I don't even know if this is the correct place to post this but I am at my wits end. 

I moved from Xero to MYOB just over 2 weeks ago and it's been an absolute nightmare. 

I somehow ended up with three active subscriptions (not an error of mine) and when I called, I was told the other two were cancelled as it was their error (already linked bank etc to one of them) and I just needed to call for a refund once the fees came out of my account for the extra two. Once the transactions were processed, I called. I spent 50 minutes on the phone, being transferred to multiple departments only to be told to lodge a ticket online. Long story short - the reply to my ticket was that a refund cannot be issued as the fees come under a promotion. 

I also have called and emailed numerous times to ask that the email limit be lifted so I am able to send invoices and it still has not been rectified - it's been over 2 weeks since I first requested this. 

Maybe this will get some results because I have absolutely had it - what a disappointing experience with a new platform!
