Query: Pet UNSAFE kennel

I purchased this kennel for my shelties. The pieces that joined it together were made of plastic and broke very quickly, I contacted the company and they told me they would send out new pieces to join the kennel together which they did, however they did charge me for them. The kennel is not sturdy, is flimsy made, the chain link is too flexible and bends so easy that even my small puppies could get out of it even though it was fastened all around. It collapsed at one point and several times my dogs were able to escape from this kennel, Do not buy this kennel as it is truly UNSAFE
