Empty promises: no delivery or refund of product

Very bad service. I ordered a Li-Ion battery pack in Nov 22 after receiving confirmation that they do have stock. On the day of planned delivery I was informed about a delay. After numerous calls Dylan indicated that they do not have stock and will refund me which still has not happened. Every commitment they have made has been missed. They never provide feedback, I have to constantly follow up with a new excuse from Dylan every time. Dylan also refuses to transfer me to a manager or director for escalation of the matter. This company should not be allowed to do business and should be avoided.
