Bad customer service

Bought a Samsung phone 2 weeks ago, only to have to take it back after a few days. Told it would be sent to Vodacom and that I would get it back within a week. Vodacom tells me they can't repair the phone and it must be sent to Samsung to decide whether or not they will replace the phone. Not once was I told that I would be without a phone for 2 to 3 weeks even though I repeatedly told the store I use my phone for business. They didn't seem the least bit interested my issue and tonight I get an sms apologising for the delay. Customer service is shocking when items need to be returned yet they are very quick to take your hard earned money. Even selling me a phone cover which didn't fit the phone so I had to return that to.
