Vodacom pathetic client service

I have been struggling to get a statement of account (November 2013 to July 2016) from Vodacom since the beginning of April. As it is an old statement I could not get it at a branch and had to call Client services. I logged a request and in stead of a statement reflecting my payments as I requested they sent me a 100 invoices. I phoned again on 19 April and a very help lady assisted me Doitumelo. She phoned me every second day to tell me that the query hasn't been finalized. She then told me that because there is an upgrade due on 1 May the query can't be resolved. I could not understand what a statement had to do with a upgrade, but left it there. She told me that as soon as the upgrade was done they will send me my statements. The upgrade was done on 1 May. That was the last time I spoke to anybody from Vodacom and I am still awaiting the statement of the account.
