Upgrade gone very wrong

Went to vodashop at Westgate mall in November for an upgrade on my top up contract that I have with Vodacom for over 10 years i had advised the consultant by the name of Palesa who assisted that i do not want to change the package as i am now a pensioner and i am comfortable with the top up package.

For the past months the debit order amount has been different every month until i contacted the call centre and i was made aware that i have a open line im no longer on top up.

I dont know how this is going to be rectified as i am not willing to change my number or leave Vodacom for people that dont take pride in thier work but i want is this issue resolved as soon as yesterday.

Very dissapointed Mrs V Ntseke
