Accessories sold by istore

I bought a cover in June from istore thinking it would last longer than buying a cheaper cover, 5 months down the line a part of the cover broke immediately the item was taken back to istore because of the part being missing the supplier was not able to fix the item however Istore never offered an alternative resolution to the problem since when does istore sell items/accessories that only last 5 month then breaks ? As to my understanding items are suppose to have a warranty on them of at least 6 month this item probably had no warranty on it, further more after asking them are they not sending the item to the supplier to even evaluated to see it the item broke because of user damage or natural wear and tear I had to suggest this to them then on top of it all they wanted to charge me to have the item collected when I could’ve dropped it off at the istore closest to me it’s now been 3 months and istore had not gotten back to me no reference was provided for the query I logged this will go down by far as the worst service I’ve ever received
