Openserve not keeping to arrangements

I ordered an ADSL wifi from Telkom and received 2 sms' ( 27 & 28 Feb 2019) stating the following:- Openserve: Dear client Mostert, Openserve on behalf of your Service Provider will send a representative to your premises - 35 KOORSBOOM CR, ONVERWACHT, ELLISRAS to fulfill your service request. We have scheduled your new line installation/modification for the 2019/03/01 - please note this is a/an All day appointment. Please ensure that you have your original ID document and/or letterhead and a certified photocopy thereof ready for presentation when the technician calls at your premises. Please reply @Yes if all the above mentioned is correct or @No if the above mentioned is incorrect and/or date is not suitable and an Openserve Agent will call you. Standard SMS rates apply. Alternatively, please visit URL http://www.telkom.co.za/appointments to reschedule the appointment.

My husband made himself available for this today and no one came to do the installation. I conracte ********** 676 today and was told the installation was scheduled for today but no technician was allocated yet. This is unacceptable and inconvenient as my husband lost an entire day's business to be at home for this

Kindly revert back to me urgently!!
