Are they going to refund me ???...Just pay me back.

I assigned Popcru as my representative Union, I called in , then the agent said I must email the cancellation which I did twice already , one before July & another in July, I called the one agent said : "Popcru will still be deducting for 3 months after cancellation"...So according to me, October was suppose to be the last payment & that's not the case I then called again , spoke to another agent, the agent said : "Popcru will give me a call back & it never happen. It's now the new month of February, I called again & again & again & different agent including a lady by the name of "Millicent" keep transferring me to another line when the call rings & then switched off. I then called after a few mins again & it seems like my phone number has been blocked...
