Game is useless

I have never in my life had such bad customer service like what I'm getting from Game Online Centurion. I purchased Tissoli pots in November and some of the stuff was missing. The courier was sent back to collect and I would get a new set delivered. I have been following up with the store and the online customer care until to date, only to be told that the courier delivered my pots to my work address which apparently I called and changed, which is ridiculous as I work from home. The courier informed the store that he was in communication with me on the day of delivery and I told him to leave the pots with the security but I was on holiday and never received any calls from anyone not even an sms sp I'm not sure who he was talking to. The address they claim is my work address is two flats from where I stay and there is no security guards there as well as were I stay. For the past three weeks I've been calling, sending emails and I'm still told they have dispatched the courier to go collect the pots and up until now no feedback. I called today and they still waiting for the pots to be collected. The customer service is useless.
