Telekom Malaysia Berhad (TM) is under investigation by the Malaysian Communications and Multimedia Commission (MCMC) for reducing the upload speed of one of its internet packages without notifying customers.
The MCMC, in a statement, said it was responding to the complaint by a customer who first discovered about the upload speed reduction for TM's Unifi 500 Mbps package.
The package offered 500 Mbps download speed and 200 Mbps upload speed. However, the upload speed was reduced to 100 Mbps.
"This complaint was reported by a number of news portals that saw the (original) offer made last month was misleading consumers.
"If the preliminary investigation finds elements that consumers' interest have been violated, the MCMC will not hesitate to take action against the service provider," it said.
The MCMC promised a transparent and fair investigation, adding that the Communications and Multimedia Act 1998 safeguards consumers' interest.
The upload speed reduction was first reported by tech news portal soyacincau.com which received a tip-off from a reader.
TM, responding to the report, claimed there was no change in upload speed, and the initially advertised 200 Mbps was a "mistake" as it was meant to be 100Mbps.
