One day only deals - Extremely BAD Customer Service

In April this year I ordered resistance bands that I required for my training. I was not able to get my bands delivered with the covid 19 pandemic and due to the bands not classified an essential. Once we reached level 4 if the lockdown the delivery on sporting accessories were deemed essential. And I acted upon the this and sent am email to One day only. I received an update that they had a high influx of deliveries they would get back to me. I received my package on the 19th of May with the incorrect set of bands. I ordered resistance training bands and received therapy bands used for people who require physiotherapy. I then sent a message on their website advising them that I received the wrong product. I received a response after a week of waiting and they asked for pictures of the damaged goods. I did not report that the products was damaged. But not what I had ordered. I then explained this again in an email and again waited for a week for them to respond. I received another email from Ashley Nagel (one day only - customer service consultant) and was told that the product I received was the correct product and I should send them photos of the packaging of that I received. By this time I am so furious. The package did not come in a branded package but wrapped in bubble wrap and in the one day only delivery package. I took pictures and forwarded this to them. I have being purchasing good online from One day only since 2017 and this experience has left a bitter taste in my mouth. The customer service is putrid. I was basically told that I'm lying by reporting that the product I received was correct when I distinctly said the product I received was not what I had ordered. Not to mention that I have not yet received a response that I will receive what I ordered and how they will resolve the issue.
