Have not been refunded

Dial-a-bed Stoneridge have poor customer service. I have submitted documentation required for a refund last week Friday, 04 May 2018. I have not been refunded to date and when I called, Natalie, store manager said they are busy with stock taking they will see if they can assist when they are done. I depend on that money for my daily financial needs. I expect full payment including delivery amount because they delivered wrong goods too. It was time wasting and unsatisfactory goods delivered.
