Poor and unfair service

I bought 3 blankets from homechoice through laybuy around the End of May 2020 that still are currently being advertised on TV and I recieved my statement saying I will pay R2000 in total for the laybuy. However I recently received a new statement stating that my new balance is R2500 ,mind you I still haven't received my order till today which is the 19th of July now I was sent an email that my first payment is end of July 2020 ,which means I have to pay for something that I dont have and somehow my total price has increased by R500.I dont know how this company works because I have been calling endlessly to inquire about my order but I hold for forever Customer service which is option 2.What's ironic about this is that when you press option one to place an order they answer instantly and that where I have been asking about my order ,and they've done absolutely nothing to help. I must say that I am very frustrated and disappointed with their service because they are active in giving statements but not active in delivering orders .This is the poorest service at it's best.I regret being part of their customers because it's not doing me any justice. I don't want their stupid anymore.
