old stock , faulty device

totally ridiculous service firstly they employ a ridiculous company like rtt logistics which is complete unprofessional.my order was processed on Friday on when I called the courier company in question they told me it would be out for delivery on Monday. so on Tuesday morning I called and had been notified its been delivered to me although I have not received any such parcel. i've had to take time off work to get hold off the parcel which was delivered to the wrong premises upon opening said parcel. I found it to be damaged as the charging pin corroded. Online shop has been called and notifed as well as multiple emails sent without much help. all I have been told was to take it to the nearest totalsports store which has been done yet... I was said to wait till Monday to check if it can be refunded as their manager wasn't in. the employee who helped me at total sports ficksburg helped as much as he possible could which was greatly appreciated... but to no avail as this seems to be like last of the stock as nothing is online. so the probability of me getting a refund for the item seems very unlikely as call center staff cant provide much help as well as online support.
