Light Duty Tire Swivel Kit

The tire kit is fine except for 3 spring clips that are missing, 6 are pictured but I only received 3. The 1 star is for the lack of customer service. On the help center under missing parts it states - 1) Go to My Orders 2) Pick “Replace Item or Parts” 3) Select “Missing Parts” 4) Tell us what part you need Well the only choices to select at this point is a full refund, partial refund or call customer service. Where do you enter what is missing? And calling customer service is useless as they don't answer the phone. I know because I tried on 3 separate times, no answer.
