Unhappy customer

I have sent an email a week after I purchased the bamboo pillows to Epromo due to dissatisfaction of the quality of the pillows and if somehow we could come to a conclusion,I then called to follow up on the email because I did not receive a prompt response from the company,I just want a refund because what you promised me is not what I received,these pillows are extremely uncomfortable especially for my partner who requires comfortable pillows due to a previous car accident,could someone kindly get to me urgently.
