Poor Service and lack of Accountability

I have been a good paying customer for over 8 years. I have 4 contracts with Vocacom and have experienced the following: 1. In December 2017 I app**** for a new line at Game Stores and requested that it gets linked to my existing account. To my surprise the new account was opened and in January 2018 I received 2 separate invoices & statements. When I called to ask that they rectify this error, I was told that it's not possible as the new line was loaded on to the new system. As a result I receive 2 statements from one company and have to make 2 EFT's every month which is an inconvenience. 2. On the 29 March 2018, I received an sms on one of my lines, saying that from 1 May 2018 Vodacom will be increasing the data allocation and pricing on Smart+ price plans & my monthly bill will increase by R47.00. On the 3rd April 2018 I called to query & cancel this as I did not authorise it and I do not need it. I was put through to different department as no one wanted to take responsibility. Eventually a consultant called Prudence Tshabalala assure me that there is nothing loaded on the system and therefore I should not worry. On the 09th May I received my bill with R47.00 increase that I queried beforehand and the 2 consultants Noxolo and Sphelele Ntamba also failed to assist. They both advised that this does not fall under their departments and cannot help reverse this charges and fix my account. I am very unhappy about the service that Vodacom staff provided to me. I don't understand why I should suffer as a result of the mistakes made by Vodacom staff. I cannot wait for my contracts to expire.
