Sportshoes.com take your money but don't deliver

 First off i have used many online services before but none as bad as this, perhaps because i am located outside the UK? Anyway i ordered 3 pairs of track spikes on 7 December 2015, confirmed by Sportshoes. as having been mailed. When following up on the delivery towards the end of the month (by way of the order number) the online system said the order was "closed" upon which i mailed them to find out what this means? Apparently it means delivery was successful even though i had not received anything on my side here in South Africa? So to try and and find out where this package was i requested the Royal Mail tracking number from Sportshoes.but to no avail as they kept on giving me the run around eventually saying that the package was deemed lost and that i had to fill in a claims form which was not intitially sent, and by the time it was sent apparently it was too late, as it had to be filled in within 28 days of the mailing date? In the mean time i also tried to get hold of senior management to inform them of the situation, but no reply thus far? My next step and last resort will be to arrange for a VISA chargeback and spread the word far and wide for people to stay away from Sportshoes.com unless there is some sort of logical explanation and they make this right and do so as soon as possible - PATHETIC REALLY? The big worry for me is the lack of a Royal Mail tracking number as it can only mean one thing - they take your money so goods paid for are not sent!
