Higher prices once contract ends!? ***

I very disappointed and frustrated. 2 years ago I took out a 5G data contract with vodacom over and above my normal cell contract since getting it I have had endless issues with bad or slow or even no connection, while this was unfortunate I think it had more to do with my area as my cell was giving me the same issues. So when my cell contract ended, I switched. And I have been patiently waiting for the data contract to end too. Now that It has expired it's a nightmare to cancel!! Firstly I did not get to cancel as contract ended but assumed it would be on a month basis and would do so when I got around to it. A nasty surprise when I get a higher bill!! From R150 a month for 5Gigs which is already ******ion they have now charged me R260!! I go to store, they are unable to assist and I must call accounts on one number and cancellations on another. I call. And wait and wait on hold. Eventually I speak to a lovely lady who tells me that the reason my bill has gone up is because I took out the contract on a special, now as it is out of contact it has gone to the normal price, R260. In almost the same breath she tells me about a special for 10 gigs for R150. Wonderful I am getting less than half the data for 60% more money! She says she will try reimbursing me the difference as I was never informed about the police going up once contract ends,not when I went instore, nor when I got countless upgrade calls. I tell her that's fine but I still want to cancel. The phone cuts . So I attempt to call back..multiple times. I manage to get cancellations number but it will only help if you are calling from the number or you know it, if not or no option is selected it cuts out, on customer care line I get disconnected once I meet the 5min hold mark. The online email query site is down. I finally manage to get through on customer care line to upgrades and cancellations but it's now out of calling hours, even though the website says 24 hours. The online chat facility is temporarily down. I am so frustrated. No one instore can assist with these queries!!!Either way I am disgusted by the ********* charging because contract ended and I am shocked at how in this day and age I am unable to speak to anyone!! I just want to cancel my contract please!!
