Few days back i have purchased AC and for installation LG service person came .After review where to setup the AC outdoor unit they have told me that they cannot install the outdoor unit of AC near to window as there is no enough space there as per their view. So later on after so many discussion they told me to install the outdoor unit in terrace where they need more pipe and additional parts because terrace is in 4th floor and i am staying in 2nd floor. After measurement they told me the whole calculation of pipe and additional things which is required as per their calculation they need 8 ft extra pipe and other materials as required which will additional cost to Rs 4450 as they estimated. Also they have told and promised to give bill copy of additional materials and pipes. Which they failed to give the bill and till date i am following with them also given complained to LG customer care but still not received the Bill copy of that additonal materials. Also later when i have checked by measuring outdoor unit of AC which is installed in terrace , i found that it can easily be fitted near to my window without any additional cost. which means they cheated me to get the additional money. So i want to complained for that AC service person who looted money from me, the installion which can be done easily without any cost.
