Very very poor service

I bought a water dispenser fridge at game Menlyn store on the 23rd Dec 2018, it was delivered on the 28th Dec 2018. I soon realized the water dispenser is not working after I filled the water tank, its leaking from outside without applying pressure. On the 31st of December I called game to lodge a query, everything was done and they sent the query to DEFY. On the 2nd of January I received an sms saying that my query was lodged and a technician will contact me soon. On the 9th of January I called the defy customer service to do a follow up, I was told the fridge was supposed to be fixed on the 7th already and was told the matter will be escalated and the technician will contact me, a week ended without hearing anything from them. I then did a follow up again on 12th January and was told the matter will be escalated again, and told to phone back on Monday of which I phoned on Tuesday, was told the fridge should be fixed by Friday and even today I am still waiting for them to get back to me. Their service is very poor because they don't even have the decency to call me but expect that I buy airtime and call them but never get assisted. Im even thinking of returning their fridge and request my money back because I reported the matter on time and they wanna take a full month just to fix a water dispenser.
