PhoneFast from Phone not Good Quality - incredibly slow and not saving videos above 1 minute

They delivered the phone on time, however there phone is not well functioning, it is like a second hand phone that was cleaned up and sold. The phone they gave me (Samsumng J6) is incredible slow and I am comparing it to the same phone they were repalcing it with. When I record videos, it does not save videos beyond 1 minute. The phone was supposed to come with a memory card (my original phone came with memory card), in the box it is written that the phone comes with memory card but there was no memory card in the phone that phonefast delivered. I do not know if they are a factory or what but I am not happy with the phone they delivered to me such that I did not even insure it agai, I will buy myself another phone from the stores that sell proper phones not what I got from phonefast.
