Game online shopping is complete disaster!!!

I bought a dishwasher from Game online on the 24th of November. I made payment on the same day and sent proof of payment to ********** as instructed, I have not heard anything since. There has not even been an email or sms to confirm that they received my payment. I have wasted my time and money calling the provided number ***, which for some reason never goes through. I eventually managed to speak to someone on the 28th and unfortunately the person was not helpful at all because apparently it's a different department and I was asked to leave my details with a promise that I would be contacted, which never happened. I kept trying to reach them and sent emails to the websupport and still did not get any response. I managed to speak to someone again yesterday and it was the same as before, some other department is supposed to do this and she could not tell me anything or assist me in anyway except asking me to leave my details, AGAIN!!! To this day, when I check my order status online it is still "On hold", this is incredibly annoying and it's a waste of time. This has been the worst online shopping I have ever had, Game should just stop with the online shopping because clearly they don't know what they are doing.
