Blinds To Go review: Refund of overpayment and design was not as shown on sample

When I purchased the blinds I was given $112.00 preferred customer discount. ( it’s on the original purchase contract receipt). The final payment did not list this and I paid it in full
April - 3 different calls to customer service promised response in 48 hours ( none I had to follow up)
Last call to customer service sent me to the area manager A week later I filled up again and the manager responded
She said the customer service notice went to the wrong email so she didn’t get it. I gave her the details and
She said she would get back to me

May 5 she said her sample book noted pattern differs from the sample but maybe the consultants book didn’t contain that. She said I was welcome to close new ones if I like. I just had major surgery so told her it will be a while before I was capable BUT I would like the refund to occur

No reply. May 8 I followed up again asking about the refund. No reply

I sent in early April copies of both contracts showing the billing discrepancies
The contract number is # 417094
More than 30 days have passed since I brought this to the companies attention all the staff I spoke with were polite but took no action or offered follow up as to why the refund isn’t occurring
