Telkom Business Struggle to support our business - 44 days and NO upgrade from 4mbps to 10mbps

On 2017/10/24 Telkom Business was instructed to change the Internet speed from 4mbps to 10mbps. (REF AI ********** ). By 2017/11/22 nothing was done - and I phoned and I received feedback via the Telkom Business Call center that they will do it within 7 business days and they issue me with a NEW ref nr (REF AI ********** ) and I was promised that they will phone me and keep me up to date. On 2017/11/29 I phoned Telkom Business Call center and I was told that it was scheduled according to the system that Telkom will phone the same day.... . On 2017/12/05 I phoned - still in status "Progress". Today 2017/12/07 NOTHING is upgraded after 44 DAYS ....TELKOM BUSINESS can not support our business!
