Less interest in helping a client

I went to maponya telkom to ungrade my contract. I was looking for an add I phone 5s and they tolde it's not available I asked were can I get it they told me any shop they don't know. Then I asked to upgrade on I phone 5 they said they don't have & they don't kn were I can get it. I asked the consultant to check for me @ which shop I can go she said she can't do that I have to go check my self. She left me there with a callcenter call for other queries. She walked out of the desk left me there and I did inform her that I will complain. While sitting with a call they were laughing didn't care I was with a call on the phone. We couldn't hear eachatha on the telephone. Laughing laughing and laughing. I went out very hurting with no assistant, I fill so lost were to go... I got home & I made a call to telkom they told me if I need a phone I must call 10213. While the consultant said If I want a cheap phone I must take sumsang and she can't help me at all.. Or call any other branch to refer me.. If it wasn't because of telkom product I would have cancelled everything about telkom. I'm very very hurting with less service of customers
