No signal, no service, no worries for Cell C

We have had 4 Cell C contracts for a couple of years now. We recently moved and the area we moved to has virtually no Cell C signal. This was reported to Cell C and it took them 2 weeks to get someone out to measure the signal. The technician found a very poor signal and reported that to them, suggesting that a signal booster be installed. Cell C phoned us after receiving this report and plainly stated that they will not be installing a booster and that we are welcome to cancel the contracts - which we can not do without paying penalties. They were not prepared to assist us to migrate to another service provider and the 'lady' informing us of this decision was quite rude. We often do not have any phone signal and hardly ever can we connect to the internet. What will happen if we have an emergency and can not phone for assistance? Will Cell C accept responsibility for that? Why does Cell C expect us to pay for a non existent service? Why do they have such bad customer service and why are their service center staff so badly trained? Our reference number was SD390548 - not even sure why they provide one as Cell C does not care!!!!! We will be contacting the ombudsman.
