Unhappiness with Vodacom

I have been using Vodacom for over 30 years. I have two Vodacom contracts, one with R200 air time and one with 5 gigs data. When I took out the R200 airtime contract, I chose that type of contract because I was renting a flat in premises with Telkom wireless internet - unlimited. I decided to take the contract as I would pay for data as and when required when I was away from the house. I do not work and I spend most of my time in the house. because the wireless internet from Telkom, which is landline based, was not great at times, which caused me to use my data and it was costing me a lot of money. I decided to get a wireless network contract which could save me from using data that I was paying huge amounts for on my phone. This was a great mistake as the network wireless signal in our area is very bad to non existent. My router sends a signal to my phone and laptop saying that I have access, but I do not have access for much of the day. when I do have access suddenly it losses signal when I am using it and my phone still tells me that I have access. I am constantly purchasing data at exorbitant rates because of this situation and my usage of data on my wireless network is left almost untouched. every month Vodacom removed unused data if I do not use it in that month, this is written into the contract, which I signed because I need access to wireless network. So Vodacom are forcing me to purchase data on my phone and they remove data which I have paid for. This system of legalised theft is unfair and I am extremely unhappy. I have logged a complaint today, not the first time. if I do not receive a refund of the unnecessary data that I have purchased, I will terminate my contracts and go to a service provider that is more user friendly. The other thing is that if you go to a Vodashop, you have to pay for assistance even if the reason is service provider related.
