Worst service ever from Vodacom

Most dissatisfying service the last 20 months, signal went from bad to Zero!! Upgraded July 2019 to Samsung A70, checked at shop in according with them signal is good where I stay! Up to date it went worse, can't even call to my vodacom number at home it simply don't even ring at all!! First complaint laid at their store in Irene reference number: *** on 31-07-2019 which according vodacom I should switch from 4G to 3G I even went to 2G even worse!! Just got a message case clsed Second complaint reference number: *** 13-08-2019 at Centurion branch Same thing called and said they know about the problem and the solution experts will attend apparently now there is a shortage of towers in the area!!! Case again closed 06-09-2019 I still have to walk around my yard to find signal!!! Third attempt case number: *** again excuse upon excuse, tower problems etc etc. This was never like this three years ago!! Mean Time I pay Vodacom every month for this service the past 18 years, now been told I have to buy a signal booster for my cost!!!!!! Really!!!!!! Vodacom person said they do not supply this for free but I pay for this service and still can not make calls to this number No Signal!!! Once again admitted the poor quality of the signal, this time advice I have the right to canc my contract which I deerly woul like to do as their competitors signal has No problem at all. This was escalated and still on progress!! Vodacom!!! take your contract and phone and #&-())! :'R@R-()!!!!!??!!! All the soppy excuses No More I pay for this service and I have Consumer rights. My MTN number which you will be able to reach me on is ***
