vaillant ectec pro 28 combi-boiler

I have just had the Vaillant EcoTec Pro28 combi-boiler fitted.I can only use one hot tap at a time as if I try to use two one will go cold.I also had the Mira Shower fitted by the same company at the same time and again if I was having a shower and a hot tap was turned on elsewhere my shower runs cold surely this can't be right.The company insist there isn't a problem ,I say there is.What do you think.Your help/advice would be much appreciated
Many Thanks
Carol
