Bad customer service and no communication and hanging up calls

they don't even deserve a star 24january 2025 bought a fridge day after delivery switched it on,and it was only getting gold on the freezer the top part wasn't i chaged temperatures until it got to 7 which it cud get abut cold but food still get spoilet and it would form a very big frost ,i logfed a return 3days after delivery and they said it'll be fetched on that Saturday no one came no communication from the store when you call they hang up the call i eventually got someone and she sent me an email to fill questions i answered, then they keep quiet i have to again call so another process has to go on and i did same thing after a while of calls not answers or hung up they saod technician will come again wait no one comes until u calm every process to be done u must fight a month later im stuck with a fridge that only works at the freezer technician cane and said i shud be replaced or refunded as its a factory fault ....it overheats one side while theother side is normal ,i ignored so many reviews about their bad service when it comes to returning electronics and i never thought ill be one of them as i shop there every month for groceries im so disappointed mostly at their customer service because when call hiesens they say the process on their side is done weeks ago and the store still hasn't called even now
