Telkom Mobile a horrible service provider with bad service

I have 4 accounts with Telkom and the one I upgraded my contract last year May. I travel extensively and last year October I asked Telkom to activate my roaming as I will be out of the country for 6 weeks. I got to my destination and roaming wasn’t activated. I was out of touch for 6 weeks as Telkom couldn’t help me at all. When I got back home my number was still not working and I had to go back to Telkom to get it fixed. In May 2022 I was again leaving the country I asked for roaming to be activated where are you in Advance. Again I got to my destination and roaming wasn’t working. When I arrived back home again nothing was working. I had to go back to Telkom to get that resolved and that was on June 7. And as I was relocating I asked them to cancel the one contract for my phone (the one I upgraded last year) and convert me to contract as it was a useless to have this number that wasn’t working when I will be out of the country for over months. Last month I received an invoice with over R1000 more. I went to Telkom to enquire I was told it’s the cancellation fee. I was told I will get an email from Telkom with the cancellation costs and that was never forthcoming. I received my invoice last week my invoice comes up to R11000, R8000 of which is charged to the number I had asked to be cancelled, but the invoice is not clear and appears like it’s charges. I then received a text on Tuesday that my other lines will be suspended because I have exceeded my credit limit. The other number my sister (who is back home is using). This morning she tells me that her services has been suspended because I over R12000, which by the where are you was Only invoices last week. I tried to call Telkom I am not getting through and sending them an email is useless as they will not respond like I have experienced when I had issues with my roaming and I can’t physically go there because I have relocated to Canada earlier this month.
