Am I the only one who is to be blamed for all these?
Hahaha! I am a senior citizen 75+. I used to use Bullworker during my younger days as it was a new item in Exercising called as Isometric Muscle trainer. I found it quite good. For the new year 2026 I decided to start exercising again and believe me this is the best all-round trainer at a very economical price. I found in Amazon an Equivalent product and Ordered it. However as a Follow-up I wanted some details about the product. Now Amazon has no Idea about how to contact the Seller and the people at the Address mentioned in the Product say that they don't sell their products through Amazon. Add to all these you can't Contact Amazon quite easily and their Virtual Assistant do not understand our problem and keep repeating the same message.Now what is the Solution?
