Very Disappointed

I had a technician from the above company come out to look at my fridge. It was re-gassed and started working again. No mention was made of any other possible problem, or gas leak. I still asked the technician to check for a gas leak. Less than a month later the fridge has stopped working again. Doing precisely what it had prior to being re-gassed. I paid in the region of R1000. I am told that load shedding could be why it has stopped working again. Last year we had many sessions of load shedding and the fridge was fine. Additionally my landlord has surge protection installed on the premises. Is it my imagination or is it a peculiar coincidence that after the fridge was re-gassed and a couple of load shedding sessions and it now no longer works - it is in fact doing EXACTLY what it was doing before being re-gassed? Instead of a partial refund (all my food had to be binned as it spoiled) I was informed it could be looked at on Friday (I work full time), with no call out fee. No call out fee - fine. But I'm curious how much more I would be charged for any repairs for faults that should have actually been detected during the first visit? It is really horrid being stuck without a fridge. I was so happy to have it working again only for this to happen - to sit with precisely the same problem I had initially. Very, very disappointing indeed.
