Disgusting service

I have a Data and router contract that is suppose to deduct R274 every month as per an agreement. All of a suddenly 31 March 2022 R391 was deducted from my account and I don't have an idea as to why they added R117 extra because I never ever topped up my data not a single month. All I need now is my balance for the router and they can cancel the data. When calling their call centere I held forever its just a waste of airtime.Can drop an email or contact me for my information to get an access to the account.
