Havells India — Unethical charges for Free installation

This to bring to your kind attention that we are the new customer of havells octet celling fan in ludhiana punjab 141001 and the experience for the 1st installation experience was very bad .We don't understand that if we want to install the new fan on the existing place than the engineer needs to dismantle the fan which is already installed and then only will be installed and for that he is asking for the extra cost which is unethical .Please take an appropriate action
