Disappointing Service after many bad experiences in the past

I am actually looking for a complaint department email address or contact number to lodge a complaint about a product that I have purchased from GAME GALLERIA twice and again the second time, this product has broke and I had a bad experience with regards to the customer service received initially and thankfully the manager did apologise and assisted me. The first aircooler i HAD PURCHASED broke and this was when I was pregnant, I had purchased because I needed it for my infant. Two months later it stopped working. I was advised that I need to follow procedure and bring it in as it needs to go through to check if it can be repaired and that I will get a call back within ten days, 03 MONTHS past and I still didn't get a response until I decided to contact the Game manager whom then investigated apologised and handed me a voucher to purchase a new one. I was without a air cooler for 03months bearing in mind that I have an infant. I then bought a new logik aircooler and couple months later, it stopped working. AIRCOOLER NO 2!! Bearing in mind that when I brought the new cooler home, there was a dent on the top and no remote, but still I was desperate and did not have time to return this second cooler. I than spoke to the manager at Game who is fairly new and he has advised me that I need to bring in for assessments which will take 10 days not bearing in mind everything that I had explained to him. I am in the customer service field and do not agree that customers should not be heard. I am a loyal customer with you guys and encountered a lot of issues with GAME GALLERIA, which I have bypassed and still purchased goods from that store. I have emails to proof all the issues that I have encountered with Game. I wish that someone that contact me and assist. My air cooler does not work and once its switched on you can hear the loud noises and just cool air that does not rotate. As a customer that been through this issue before I should just be told to bring it in, something should be done to speed it up. I have had goods that were damaged and because of past experience I was told to bring it back and given a new item or voucher immediately, I can even name drop these managers of whom assisted. That is what customer service is about, to hear your customer out and try and better the customer service level considering their past experiences. That is reason why I still shop at Galleria. The manager that spoke to me was Sheldon WHO did not really seem interested and just said bring it in to get assessed after explaining my whole experience. I unfortunately will be taking this up further and on hello peter as I feel this is unfair and managers are very inconsistent. There's no going the extra mile for customers. Remember I paid for a product that is broken not even a year.
