Invoice

I call Mtn ccc to advise them that i have not received an invoice since i took the contract on September and i spoke Portia who had an attitude who i wounder how can she be in a conact centre with an attitude like that, she even promised that she will send me the invoices for the past months, but she did what i expected she did not send it and the ref no that she gave me is ***. And i had to call the cal centre again and spoke to Jayson who promised to send me the invoce but he did not send me until i called for the third time and asked to speak to a team leader Chad Alexander who was able to send me the invoice, how ever am still not happy with the service i received from the two consultnt only if i knew that is how i will be treated then i would have not bothered to take the contract
