Shocking service and breach of contract

Was cold called, concluded a in principle contract telephonically, requested a hardcopy to be sent, never arrived. Delivery should have taken place during leave time- never materilized, asked to be called when delivery to take place, never happened. Upon reciept instalation to have taken place- never told about limit thereupon , made it clear that had three system installation. Asked for recordings never materilised, arrangements for instalation not honoured by installer. Since then despite requent for management intervention - fobbed off . Reply that barnabass would get back to me. - call centre refuses to escalate.
