Poor service on LTE cancellation and or any communications

I'm trying to cancel LTE service , within 7 days cooling off period

Telkom confirmed and promised connectivity at my home address. After no to little connectivity , I took action and called them to find out how to cancel this service. I followed exactly those steps

I knew Telkom's service is not very effective and went into a branch to cancel this service and obtained a reference number. This action was followed by sending normal cancellation form to ********** I also followed up by phone and received sms notifications as well , of query being looked at and later that it was resolved.... Obviously this was not done and is still struggling and cancelling debit orders bi-monthly.
