No refund and no customer service from the Mattress Company

I have been waiting for 4 weeks for my refund, despite being told it takes 7 to 14 work days. The past week I have phoned everyday for an update when I am either told I will.be phoned ask with update, or person who will update me is on leave or that same person is busy and will call back, which never happens and if I am lucky to speak to the lady I am told she is following up with management who must do refund. Which is also a change to Monday's story of the refunds get done by head office. Seems now one is interest in assisting or care about the lack of customer service. Ironically, they were way more helpful amd available to assist when I wanted to buy something
