Still fighting for a refund

I ordered something on the 26 September 2017. The amount went off my account but I got an email from Spree saying "My order has been cancelled as payment was not received." I sent a few emails which got no response, eventually having to phone them.

Each time I am told a different story which ends up in being that I will get refunded yet I am still not being refunded.

I was told they were previously having this issue (must be a system error) yet I am not being helped at all. I have sent proof of payment and explained myself to several different people yet still I am not being refunded and it is now the 12 October.

I am feeling very hopeless about this situation as I feel I am never going to be refunded money that is owed to me.

Will definitely never buy from Spree again!
