Trudon: Contact number

I am invoiced monthly via my Telkom account by Trudon for two items, namely i) Web 2050 Info3 IYP and ii) WP 2022 Durban WP (DBN). Services that I don't want and have no record of applying for. I have been trying to contact Trudon to cancel these services, but cannot find a telephone number or email address that works. Can anyone provide a lead or assistance.
