Agree to what you say. But you have to consider customer's side also.
How can the customer be penalised if the LNB supplied is faulty and becomes defective within one month. If TS does not provide a simple minimum warranty for the equipment it supplies and customer has to pay for repeated defects of same equipment within a short span of time, I am afraid it amounts to malpractice.
If what you say is correct and there is no incentive for the technician to honour equipment warranty, the business service model itself is faulty.
