Muziwandile Hlaba NOT DOING HIS JOB

On the 31st of October 2019 we went to Menlyn Mall Telkom store to upgrade our service from 400GB to uncapped. On the 15th of November 2019 I phoned 10213 around 08:00 am to follow up. I spoke to Muziwandile Hlaba and he confirmed that the order is placed and that within 7 working days someone will contact us for the upgrade. From the 15th till now NO ONE has made any contact with us regarding the upgrade. I phoned today (04/12/2019) to follow up and the gentlemen I spoke to confirm the order is there but Muziwandile never processed it. This is now been over a month that we are waiting for the upgrade of our service. We are loyal customers and always pay on time this is unacceptable that we have to wait so long to be assisted. I would like to put a formal complaint against Muziwandile for not doing his job.
