BEWARE GAME ONLINE - they do not care about their customers!!!

I have experienced extremely poor customer service from Game Online. I bought a washing machine online on 26 June, and then cancelled the order on 29 June (as I had found something else). At first the customer care call centre people were very helpful and a week later called me to find out my banking details, which I emailed through to the *** email address (this was around 15:30 on Sunday, 5 July). The same lady called me the next day to say they had not received my email even though I had received an automatic response from their email system. I then sent it again on Monday, still to no avail. Then, the lady asked me to give her my details telephonically to send through to the refunds department, which I did. I then called on Thursday, 9 July to find out what was happening. The lady (this one's name is Jolene) said that someone had emailed me to get my banking details, as they could not take them from the other lady who had received them telephonically. I said to Jolene that I had not received any email from anyone (apparently someone called Navene). She said she would email me from her address. I mentioned that they may have my incorrect email address (no idea how tough as they had my details from my online account), and she refused to check it with me and said they had the right one. I asked her to phone me back in 30 mins to check if I had received her email. She did not and I had not received an email. I then called on Friday, to speak to another lady and I made her check my email address on their system, which turns out WAS WRONG! She then managed to locate my emails with my banking details and said she would send them to the refunds department and come back to me that same day on what was happening. She did not. I then called on Monday, 13 July only for someone to tell me that they now needed my proof of payment. You have to be kidding me!!! It was an online order, paid through their online system???? I lost it with the lady on the phone and put the phone down on her. I had put two requests through on the online system with no response to either. This is simply UNACCEPTABLE. As a single mother with two children, I need my money to be refunded - this is my money, not theirs, and they simply DO NOT CARE. I will never, ever support Game stores or their online platform ever again.
