I have got feedback from the manager today, and sorry that we cannot make the payment until the problem is solved. After repaired and sent back from your place, the refrigerator still cannot work normally. Before it was broken, the temperature was alway below -10°, even changed sometimes, it had never gone above 0°. Now the temperature keep changing frequently, and goes above 0° many times in a day. Under this situation, we cannot use it normally, for example, we cannot put frozen food like frozen dumplings, frozen pancakes in it. So we hope some mechanic stuff could come and check, and get the problem fixed. Thank you.
