My cousin applying relocation of his TM last December also almost kena charged. At first the contractor asked RM70 for the installation,padahal TM port located just at the front of his new house.
He repeated back what the TM customer service said to him that there's no extra charge for the first 50 meters of wiring to house. Next meter would cost RM2.50 and no other extra service charges.
Luckily the contractor said ok and set up the appointment next day installed everything FOC for him.

For case like this better just wait for different contractor and get their opinion about the damage.
