No support Bad Sales persons

I bought a HD Monitor with 2 HDMI ports I told the sales person that my client has a computer with only a VGA display port, The sales person made me buy the wrong product and told me I have to bring my clients Computer so that they can test it, when I told them I cant bring the clients computer they refused to help me.

I decided that its better just to ignore it and buy the correct product because my client is very Important to me, now the sales person's is still trying to sell me the same wrong product when I need the VGA to HDMI the stock code for what I need is 177351 . He is still trying to sell me the HDMI to VGA 1****7 what I have bought before and it does not work.

Sill no answer from them when I am trying to call them for the honest 16th time
