Totally waste of time and money you spend. Customer care is useless and doesn't care about the promises. So if you want to buy anything, don't expect any help from customer care or sellers as they don't care of any ratings. I was promised to get a refund and no response even after following so many times. By the way refund was not even 10% for a faulty product which does not work. Spend more than GBP 600 to promise refund of 50 and got nothing back.
