Dropped Calls - No Signal - Unable to use device

Good Day

I have recently logged a complaint with Vodacom Customer care regarding the use of my mobile device on contract with them. Signal is so poor for the past 2-3 months in our area that I cannot make calls or use my data. If I succeed in making calls , every 30 seconds to a minute they drop. I get a "10 minute" free every now and then to compensate for the dropped calls , but only over weekends when it has no use to me. Anyways don't have a use since I cant even make calls in anyways. I reported the matter on 22 September 2017 and haven't heard a word from Vodacom since. I escalated the matter in the meanwhile , with no success. I use my phone for business and currently affects my work. if there is no Wi-Fi from Telkom or someone else available I cannot get any work done on the phone.

I demand a refund for the months of bad service as the phone has no use to me. But still every month my money is good enough to deduct ?

This is not my only contract - i have 4 with Vodacom and still experience the same problems on the other's aswell
