They should honour their agreement

I took the DSTV router with multichoice they are debiting my account on the 26 of every month now I am having challenges to get mu day data as promise they only allocated night data which works from00:00 -05:00am... I have been calling them everyday since the 27 of feb requesting them to put in my day data amd it's not in till to date...they are always telling me to wait for 3hrs or 4hrs it will reflect but nothing it's happening, and they also told me that the matter has been escaleted to the relevant department but nothing it's happening..I am so disappointed by the way they are conducting their business.
