Telkom Mobile - NO ANSWER OR HELP WITH BLOCKING AND REPLACING A PHONE

I was ****** from my Mobile Phone on Thursday 4th of June 2020. I have tried to block my phone which is with Telkom Mobile unsucsesfully since then, We have been instore at East Rand Mall, Carnivall Mall we have called to Telkom and have hold on line for more than a hour at a time every day today is Monday the 8th . To date no one has answered a call, or helped at a branch. I have Insurance on my mobile but cannot seem to get my phone blocked and replaced. Has Telkom closed it doors to the public??? Yet they make sure to Debit my account every month. My Mom is with Vodacom she to had been ****** from her phone on the same occasion as me. She was able to block her phone with in a half hour and have it replaced the following day. Needles to say I am siting with the WORST SERVICE PROVIDER...... please can some one help!!!!!!!!!!!
