Vodacom underestimates client history

We are located in Joostenbergvlakte and complained about signal. Technicians were sent out and the conclusion was not enough signal towers in the area. Vodacom says it will take between 18 and 24 months to rectify. Until last year they were giving signal boosters to clients experiencing the problems. Now you have to purchase one at the price of R7000 . It only has a 10 m range claims the consultant that assisted me today. We gave been customers of Vodacom since 1996 - during thr early 2000’s my husbands account was between 6000 and 8000 per month - now I have to pay the same as the person who wants one and only joined Vodacom in the last few years. Where is the customer service. This is right next to the N1. There are going up huge businesses. Surely it must be a sound investment. MTN gave me a free router !!
