Pathetic Client Service

My wife has a contract with Vodacom, which should have expired in June 2020, she received a call from vodacom (later confirmed by Vodacom to be buymondo) for renewal in May , which she declined, although her account was R160 monthly, a deduction of R834. 00 was done by Vodacom. She immediately took this up with her nearest Vodacom branch on the 17th of June 2020, a complained was lodged and it was confirmed by the Vodacom staff that Peter from buymondo on his own accord entered her ib a new contract. After several calls and visits to the Vodacom branches since June my wife still get accounts and amounts still gets deducted from her account, a Joseph should have called her the end of July 2020 with regard to the finalization and refund, she unfortunately is still waiting for this call. Several calls was made to the Vodacom call centre, but my wife is send from pillar to post. Nobody in this company takes ownership of the client's queries and unfortunately there is no management who the client can inform of there frustrations.
