Super General Company Complaints

Hello,

I purchased a cooker + oven 2 years ago from Lulu Wahda Mall in ABu Dhabi and I got problems in the oven few months after the purchase. Unfortunately I lost the receipt where I have the warranty but I called the customer service and one person came and said that "he fixed it". He didn't change any part and I paid for the visit. few months later, the same issue happened in the oven and I called again the customer service and they sent me someone to fix it and of course I paid for it. I don't know what he did but the oven worked for 3 months and again stopped working. I called the customer service again and I complained because every 3 to 4 months I have the same issue with the oven and every time I have to pay without results.
I need to place a complaint against the customer service center in Abu Dhabi, MUSSAFFAH AREA because they are unprofessional and cheating on people with the repair they are providing.
