bad service when i want to buy a new product

I went to my local telkom store to get 2x wifi routers that are on promotion (R99 for 5gb with router) but it is always out of stock. According to the lady that helped me the deal has been discontinued. I phoned the customer care services to order but they only take my number and never comes back to me! This is the worst service ever! I'm struggling to buy a new product. Due to this I'm considering to cancel all 3 contracts i already have with telkom! I never get good service or someone who really wants to assist me... Telkom needs to work on the customer service and relationships they provide... call me ***...
