Vodacom repair centre KZN

Vodacom repair centre is the most appalling and pathetic one could ever deal with. Being a business customer I had to follow up and follow through continuously to be advised that the sms messaging administration system is malfunctioning hence no communique regarding services. Services is restored however to date I am still awaiting feedback. Their consultant called me to advise the above after I formerly mentioned I will be logging an official complaint about their service delivery. The branches try to contact the repair centre of Vodacom to no avail, I'm cc in emails to no avail. Literally the management requires to urgently investigate service delivery to their business clients.
