Terrible service

What disgusting service I received from these people today I searched for fridge repairs on google and got them and they give the option of contacting on whatsapp. My fridge just stopped working and I have no idea what went wrong I then messaged them on whatsapp as we are given that option and the guy was unwilling to help me he asked me questions I had no idea about I told him that I am not sure and he tells me I have to know these things and will not quote me over the phone and proceeds to block me. Instead of assisting me in kindly telling me how I can find out the problem or atleast telling me that they will have to come for an assessment perhaps to quote me.
