Poor Service

I bought a refrigerator last year may and this month of January 2021 i reported it as it was not getting cold the technicians came on the 18th and 19th so they had asdvised that the refrigerator had to be replaced they wanted proof of purchase and they had sent it to the service manager Eddy i then followed up with a call they kept telling me it is awaiting approval from the manager i called the next day and it was the same story i then spoke to a lady Logan she also confirmed that they are awaiting the approval i then asked to speak to the manager directly i spoke to Eddy the manager he said he was authorising it as we were on the line and it will be sent to Logan for processing i then called the following day and to my suprise Logan said she is awaiting for approval from Eddy still i then said i will follow up but Eddy has not been taking my calls and when i speak to the receptionist she said he is in the office i then asked for his email address but it was incorrect i called the switchboard again but they gave me another email address of which came back undelivered i then tried calling Logan her phone is switched off i am honestly upset will never again buy this brand they are unrealiable just like their products
