******** block of cell number

On 29th June I received an sms from Vodacom saying that full admin lock had been activated!! Turns out it is NOT on my cell number but one of my tablet devices. I have had the number for at least 10 years and use it for reading only. NOBODY has ever communicated that if i don't use the tablet for calls it will be blocked and deleted. Now I must go to the police station to make out an affidavit that it is still my number. Well I am over 60 and am not supposed to go out- Covid -19!!!! I am absolutely furious. How dare they do whatever they like. This is not my first issue with Vodacom and cannot believe how they are an absolute law unto themselves. It would have been useful to tell me the number that they have blocked on the sms but no they did not. So forget Vodacom when you need a cell phone!!!!!
