Hello, I was a Digi user for at least 5 years, for the past week my internet data is very very slow, and always drop from 4g to 3g, before this I don't have any problem, my address is Taman Tasik Utama Ayer Keroh, Taman Bukit Melaka, 75450 Melaka. I'm quite disappointed by the Digi service right now, is there any improvement that will be made for this problem? [protected]
