Telkom Mobile Deteriorated 300%

They improved 200% up till 2019, now they have deteriorated 300%. The accounts department is not reachable, and the customer care is useless and they are the only reachable department.........well till last week, because now they are unreachable. I try to top up recharge, and the voucher is rejected, try internet banking recharge it is returned after trying 3 times. Fortunately I also have MTN else I'd be doomed.
