POOR SERVICE FROM OBAKENG MBONANI

I took 3 devices from Telkom centurion same day and Obakeng Mbonani who was assisting decided to open 3 different accounts instead of one. Meaning should I have a debit rejection I will be charged 3 times because he decided to make sales by making 3 different accounts. Secondly I asked him multiple to ensure that he sets my spend limit to zero and he confirmed that all phones were set to zero spend limit....I am now receiving multiple invoices and my spend limit is sky rockets.... I am so annoyed with the service from Obakeng Mbonani!
