Appliance Repairs Job - Mamre, WC, 7347

I moved from Kuilsriver to Mamre. Before leaving my fridge although still working, but not at its best. I was advised to have the gas refill. I arranged with a company and the send some one. The person replaced a smallish copper unit and refill the gas. It worked properly. On arrival in Mamre, the fridge did not worked. When it was refilled with gas it worked for only 5 days. Subsequently I bought a 2nd fridge from the company that last refilled it. It. However after 4 months usage it also just stop working a week ago. One Defy and one KIC.
