Shocking customer service

On 8 August I ordered and paid for two items from Rusell Hobbs online. My order number is 5835. On 17 august only one item was delivered. I inforned RH via email immediately.

To date I have had no courtesy of a reply.

On 23 August I called their helpline - all agents too busy to take my call. And sent a follow up email. On 24 August I called again and received the recorded message that there are no agents to take my call and the BEST option is to contact them via their e-mail address. This i have done repeatedly as stated but have had no response.
