no delivery no update

I Ordered a phone online on 30 March 2019, got a call to confirm all details on 04 April my account was debited and got an sms that I should expect delivery within 3-5 working days and also given refence number . Friday was chatting with one of the consultants she says its on credit vetting , I am surprised how can they debit while still on vetting and confirm delivery , I wrote an email no response , called no answer. today was promised to be consulted no one did. this is very bad worse service ever. I regret ordering a phone from Telkom.
