Hisense no reply and no stick

I have been phoning and writing emails back and forth for weeks to buy a main board for my TV. Yesterday i phoned and they finally had stock but i had to email again! Today out of stock sorry i have to wait 2 to 4 weeks again! This is horrible service i wont advice anyone to buy hisense products. When theres a problem nobody will get back to you and everything will be out of stock.
