Please take us seriously!!!!!

I regret the day I ever joined Vodacom!! I have a data contract with you guys but for the past couple of weeks I have no signal through my Simcard, I struggle to receive calls/make calls and have to hotspot through a phone with an MTN sim to have access to internet services. This means I am unable to use the data I receive and pay for, I have since asked Vodacom to cancel this data contract since they cannot provide me with the service I paid for and cant seem to sort out the issue so I can switch over to a different Network provider but they want to charge me a premature cancellation fee of about R11000 on a R200 contract that they themselves confirmed is expiring in April. Why should I have to pay a cancellation fee when you guys fail to offer me the service i signed up for and cannot seem to sort this problem out, my neighbour who also uses Vodacom complains about the same problem but you just do not care that your customers have no coverage. I refuse to pay this cancellation fee, you need to either waiver these fees and let me out of this contract because you cannot keep to your end of the deal or you sort out this signal issue. I receive 60 GB's of data and have only been able to use 7GB so far that's how bad this is but my money keeps getting debited each month
