DHgate.com complaint: Didn’t receive items, nor a refund!

In mid 2020, I purchased four items to the value of AU$43. This was done online through www.dhgate.com. I waited for a number of months and I never received the items. Nor was I offered a refund. During the following months, I became very unwell and consequently was in hospital in November (I have the paperwork as proof). This didn’t allow me to follow up on the status of my order with DHgate. Earlier to mid this year, when I was feeling better, I contacted the DHgate Customer Support service. Their responses were very slow and they would often take longer than a week to reply. Sometimes they just wouldn’t reply at all. Their service in general was quite unhelpful and poor. Ultimately, they informed me that, as the seller is no longer registered with DHgate, they cannot pursue them for a refund. They contacted the seller and heshe did not respond to them. Hence, DHgate was not able to offer a resolution and the case was closed. This finally was concluded last week, after the constant messages on my part were ongoing for several months. Quite unfairly until this day, I never received the delivery of the items nor did I receive a refund. I believe also, that DHgate never made an effort to try to provide a refund to me.
