Dsv biometric not working

My mtn package was supposed to be delivered last week Wednesday 17 august unfortunately on Tuesday 16 august i was a bit busy and i missed their call but i had given them an alternative number which is a landline to avoid such thing. They phoned on Wednesday the 17 and told me they will only deliver again this week Wednesday 24 since they only deliver in my area on Wednesdays only I ddnt have a problem because I missed their call and it was my fault. Yesterday 24 the guy came upon delivery the biometric failed to pull through my thumb so the guy left with my parcel and told me he had tried i must contact mtn to arrange an otp method since biometric failed. I was so upset because i need the cellphone and the guy was impatient he tried 3 times and he said he needs to rush there are many deliveries he has he can’t spend the whole day with me. Right now I have to wait for next week Wednesday again before i can receive my cellphone. Upon explaining this situation with my colleague she told me she had the same experience with the biometric of dsv fortunately for her she had a patient driver who tried several times until it was successful but in my case i was not lucky. My plea to you dsv please upgrade your biometrics to make the experience seamless and again this thing of you only delivering cellphones on Wednesdays only is really frustrating because the other dsv car comes 3 times a week to my workplace why not train all your drivers about biometric so that they can be able to deliver cellphones this can save you costs as well. Im really upset with this experience I hv to pay for the cellphone that i hv not yet received and used due to your fault.
