Dear T-mobile team,
I left the Netherlands in 2015 but still have active t-mobile number (Abonnementsvorm: SIM Only, Tariefplan: Basis Sim), which I use for receiving SMSs from the ING Bank.
Now it is time to close back account and I'd like to cancel my contract with t-mobile. Unfortunately, after logging in to my t-mobile.nl, I could not find any corresponding option, where I could cancel the contract (Beëindigen en annuleren) myself.
I will appreciate any help from t-mobile team to cancel my contract and deactivate my mobile nummber.
Please let me know whether more details (mobiel number, Clientnumber, etc) form my side are needed.
With best regards,
