Bad service, loopholes to escape damage done to customers

I think it’s very shameful that companies will actively recruit customers sign them up for whatever they are selling, overload them with information and then when the customer later complains they say oh but we explained this during the consultation. How when things can be missed during calls and despite the customers dissatisfaction the business stands on its ground and leads with we told you based off a phone call where things can be missed. Business that just want to ensure they profit are just glorified ****mers and affinity is no different.
