terrible service, rude manager...

I bought a phone which in I week was malfunctioning and I took it back to Dion Wired at The Grove mall. on first attempt I was told that though I bought the phone there, dealing with a phone matter was not their part and I must take the phone to Samsung store which was closed for the day. The next day I went to sumsang, where I was told that I was misled and must return to the store. Being very upset at this point I was kept waiting for over half an hour during that time my faulty phone was looked at by 3 guys who clearly had no clue what they were doing and reset and rebooted the phone multiple times after which the phone was not even responsive past switching on, to my disgust my airtime was used up during their probe. waiting there over half an hour, came the admin manager who I discovered stood inches from me most of the whole time. she was condescending and quite dismissive and I am beyond angry. I left not knowing when the matter will be resolved, without the phone and I am still angry. The highlight was the cashiers who typed a document I signed.
