Multichoice Pathetic Service!

Regarding the Multichoice Migration. My Mother is a pensioner and enjoys and regularly watches M-Net. We contacted Multichoice on 1 March 2018 as Multichoice is migrating to High Definition from 1 April 2018 and your M-Net will be "switched off" by 1 April 2018 if your M-Net was not upgraded by Multichoice and their contractors. We spoke to Sheelbooi at Multichoice on 1 March and he gave us a reference number. On 2 March 2018 Maxine, from Multichoice, phoned and said that we could expect installation within the next two to three days. No one contacted us for installation. On 8 March I phoned Sheelbooi again and he said that they were very busy and that we would be contacted soon. On 26 March I spoke to David at Multichoice and he gave us a new reference number. On 2 April 2018 I phoned Multichoice and spoke to Othilia. She said that she would follow up and agreed that Multichoice's service regarding our complaint was unacceptable. She sent me her e-mail address. I have since sent three e-mails to her and have still had no success. Multichoice deducted their premium from my Mother's account at the beginning of April and she still has no M-Net channel!!!
