Check my grammar: dear mr. peter szulczewskisubject: loyal customer’s complainti visited wish.com last month and found a 2-terabyte hard drive for only $69.99, an alive aquarium piranha fish for $7.99 and an unlocked samsung galaxy s9 phone for $599.99. the price of such quality item got me to buy all three of them thinking it is exactly what the description and pictures shows it be.the items arrived today and i am for giving me an actual samsung galaxy s9 for a low price but i got lied about the two other items, i know it doesn't always happen but we are losing our trust everytime it happens. i got 500gb hard drive and a plastic sardine fish. i thought i saved money but a 500-gigabyte hard drive should only be worth $40 and i am ok that they gave me a plastic fish because it is only $8 but they gave me a sardine plastic fish which is a very uninteresting species of fish and i have no use for it. you again for the phone. i like buying in your website and admire the prices you give to your items. i will not ask for a refund for the fish and hard drive but you should tell your sellers to use a truthful descriptions of their products because if they keep deceiving us, you might lose a lot of loyal customers.sincerely,russell john javierloyal customer
