Cannot get an answer

I get mailed an offer to migrate from lte to Fibre. The consultant was great. About a week later fibre is in. I get invoiced for lte, then today for fibre.(zero rated as per the contract for 3 months). The consultant stated that because it was migration the balance of the lte contract falls away and the fibre for 24 months, kicks in. The lte is still active. The 10210, the 081180 go in circles. Online chat, the consultant says I must cancel the lte online. So I log in....5 attempts later the website works..... I select cancel. Now it says I may be liable for penalties????? This was a migration done by you....Telkom. I have always had good service. Covid is not an excuse for not answering mails, and for looping 081180. Please get someone to call me to sort this out.
