Homemark Do Better.

I ordered the Milex Infrared heater on the 25th of April. They had promised to deliver the heater after the lockdown was lifted which I assumed was level 4. On the 29th I received an email saying my order was on the way. I waited and waited with no response from them. I had to call them to make and enquiry. I was made to wait on the line and was told they will call me back. I waited and waited and made another follow up call. They then told they were out of stock. And my question is why would they take my money knowing very well that they do not have stock? I find this gross misresprestation on their website unfair. And they have the audacity to tell me that they only process refunds on Thursdays only. What am I supposed to do in the meantime. Since I want to purchase elsewhere. Winter is approaching surely by the time I receive my refund the prices would have hiked eleswhere. This way of doing business is unacceptable. The payment process should not go through without the store having the ordered stock. It creates a huge inconvenience for the buyer. And the waiting the period for the refund is also one-sided, it feels as though I owe them money when it is the other way around.
