Worst Customer Experience

I had the worst customer experience with Homechoice. I made an online cash purchase on the 22 April 2018 till this day they claim to have not received my payment. I call them daily and most of the time they hang up. I have email my proof of payment to ********** 3 times already and they have responded that it was received. I later received and email that my order is out of stock. I changed it to something else. I started receiving sms's that I must send proof of payment which I did forward again. A few days ago I received an sms stating my order has been cancelled due to not receiving payment. This morning I log in a new order has been created, dated the 14th May 2018 with an amount lesser than what was debited from my account. The sms harassment has started again threatening to cancel my order if I do not make payment in 5 days. Order number ********** 0 now changed to ********** 9
