Payment update

Good evening

I been trying to get hold of someone to assist me with regards to my payment update on my account.

My account is under my sister name mariam ali So I took out an laptop with Telkom and I have one more payment to make before it closes off.

I received a statement on the 5th July 2021 saying I havent made any payment to the account. My last payment was made on 30th June 2021 for R500.00

I just require someone to assist me with updating my payment and sending the correct updated statement.

I tried using the telkom chat line but no body responds... asked them to give me a call but no one is on the line... I do not have an email address and km struggling to get through via customer service line for assistance.

May someone assist me please... My sister number is *** to locate her ... it's for a laptop that will be ending soon.

Kind regards Sulayla Ali
