Dear Sir/Madam. I have purchase 杰夫人 cleaner in total cost of amount rmb2,000++ on dated 18the June 2020.order number;107094****65673**** Few day later I message seller to know the delivery date, immediately on the same day the seller have block/blacklisted me. I have realized that they have increased the price to 100% now, since I have place ordered before the price rises, there is no reason for me to cancell the deal and also I have waited so long. I find that these is a NASTY and untrusted retailer to sell product in this way, it just like you bought a house at low price during convis19,later convis19 was being control and price went up, and seller refuse to deliver the house. I have complaint these matter to taobao many times but no action being taken only ask me to apply refund. Just like I said buying house story. I have no alternative way to seek which authority csn assit me. I hope by writing this email is to feedback about nasty retailer should learn the lession. Your truly 麒力骨美i ib
