Shocking service

They repaired an air con for us and when the problem came around again they came through had a look agreed that the problem was with their workmanship.<br> <br> It has been over a week and they don't bother to answer our calls, reply to our emails nothing. They have no regard for what good service is and I can't believe that they can have a business based on these conditions.<br> <br> Needless to say I can't even call another supplier because the part they have supp**** is under warranty.<br> <br> Absolutely shocking.
