poor warranty repairs

I registered my wachine machine for its extended warranty, it broke in February and they sent someone out to repair - he stated it was not broken despite the drum being loose and the burnt smell of wire. Last month in May same thing happened, I logged the repair again, last week thursday two guys came claiming they from hisense to repair the machine took pictures of the machine had me sign a piece of paper (not authenticating themselves properly) and said it is infact broken and they will come and take it and have it fixed, I have emailed, YOUR CONTACT CENTRE NUMBER PROVIDED DOES NOT EXIT WOW and no one has gotten back to me regarding the repairs. It is winter, the clothing is piling up, how many times must it be repaired I want this sorted asap and would like a new machine as clearly you only fix it partially to allow for the constant repairs
