Basic customer service non existant

Tried to port my number from Vodacome to MTN - sent the request 3 Mar and received an sms stating that it was declined. Went to Vodacom4u Cresta mall the next morning- was assisted by Taffy who advised to wait 24 hours and to call back if unsuccessful.

Could not get hold of her and was assisted by TK who informed me that they were offline and would assist once they were back online and would give me feedback thereafter. No feedback. Called him the next day and was informed that they were back online and he would assist and call back thereafter. Still no feedback. Called again - he was on lunch, left massage - no feedback.

Is it not basic customer service etiquette to give feedback once it has been promised?

It is the 16th and I still have no idea why my port request was declined....

Vodacom - you need an additional landline - the line is engaged 80% of the day which makes it very difficult to follow up since your agents are incapable of giving feedback
