any one have an idea how to get back my old number? since the center had told me is already recycle and no way to get back.

Call the person using your number?

Buy back the number at the Telco center...

If cannot, then contact the person who bought your number.... See if he / she wants to sell or not....

If buy back, can chg owner name ?

Should be no issues...

Usually 99% the new owner won't sell unless the price is pretty high. Someone I knew paid over 10k for her old number back simply because it was very memorable. The fella selling it suddenly struck 4D jackpot for nothing.

i had been trying to call them but whatsapp and call no answer

well i not fond of that number anymore, just that all of my whatsapp backup is tied to that number and i want to retrieve it

How to ensure that
If sell to him then he doesnt chg it then anything bad happen back track to u again coz u still owner
