Stupid conditions

I upgraded my dad to a Cat S30. His first Android phone, thinking it would be perfect, being rugged and well developed. He used it for a week then he phoned and told me it's ****. I said it's fine take it back to vodacom, because of their 7 day return policy. Apparently Friday to Friday is 8 days even though he didn't start using it till Tuesday. He's a working man, with a constant need of a proper device but now vodacom has locked him into this. He's been at vodacom for 20 years if not more. I simply want him to be able to return the product he can't use back to vodacom in exchange for something he can. Give him the option. Poor service and shame on you.
