Multichoice pathetic service

I am not happy at all with the service of Multichoice. They are unprofessional and full of lies. They recently called me with an offer to upgrade my decoder to explorer that I agreed and had a contract that was in place already that they promised will remain in place although I will pay extra R150 for the explorer. Come the day of installation the instalment immediately changed with extra charges for cancellation then I called on the 3rd of November and spoke to Galada Zethu who promised to reverse the cancellation charges that were added by mistake and make sure my Account will reflect the correct balance by the following day, nothing happened until I called again on Tuesday and spoke to Andiswa Kwane who promised same thing and I insisted to speak to her Supervisor and she said is busy and will call me back. Up to now no one called me and the charges are still reflecting at the same time my Account balance was never rectified.If Multichoice cannot resolve this I offered them to come and collect their Explorer and connect my old decoder. This is pathetic for such a big organisation just to resolve a simple issue. If this issue is not resolved urgently I am cancelling my Account with DSTV immediately and must come and collect their decoder.
