Sold lies

I recently app**** for a Huawei router package for 5 gig daytime and 5 gig night time for R149. The consultant (Precious) then told me that they have the same package for R99 which I signed up for. The router came on Tuesday the 19th and by Friday the 22nd the data was finished and I don't understand how. I received a messenge saying I have 500mb anytime data which is not what I signed up for. I want 5 gig.

I signed up for SmartInternet - 5 gig not SmartInternet - 500mb. When I call to enquire I am told 5 gig was loaded which is a lie.
