Online purchase items not received

I made an online purchase and I received a confirmation email that my order was being processed on 07/09/2017. Till today I have not received my goods. I sent a follow-up email on 29/09/2017 to ********** and I have not received feedback or any acknowledgement that my query was being attended to. This is really poor service by their standards and I am really disappointed as this was the 1st time I made an online purchase through their app. I honestly would not advise anyone to make a purchase from them online.
