Extremely Bad service.

Vodacom recently did an upgrade on 2 of my contracts. Telephonically and a quote invoice was sent stating the amount to be charged which included FREE CLi. Now the invoices raised exceed the agreed amount. Despite phoning and emailing them they have not resolved the issue. Several references have been raised and within hours we receive notification that the tickets have been closed. Yet they have still not resolved the problem Having been clients of theirs for over 25 years I find their client service absolutely atrocious. I am extremely disgusted with Vodacom and am now taking up the matter with NCC. I have phoned them on numerous occasions and always have to deal with automated system and then get placed in hold and eventually the call us cut. When you try to get through to the upgrade division it cuts the call after informing you that you are not due an upgrade. How are you supposed to get the matter resolved when clearly they don't know how or are to lazy to sort out the matter. Will never recommend them to anybody ever again. Will highly recommend that other cell service get used.
