no it is true. the reason they reject to service AP set is because, some ppl get their AP set serviced in service centre, and some AP company count that as void to their warranty (when the ppl go to claim, or further servicing fromt heir ap company). the ppl 'beh song', go back to SESC and express their frustration like no ppl business, and hence SESC have the right to refuse servicing AP set, since that might void their AP company warranty.
