Most terrible service I experienced

I have had the most terrible experience deal with Vumatel. Sales consultant Goodness Mashaba really needs to be up skilled with delivering of customer service. I kept liaising with her on watsapp for installation, was told the company had tried to contact myself or my husband but we never received calls but there system reflects attempts to call this was before the long weekend from 26th April was waiting for installation. To take up the sale and debit a persons account this was done same day but the service delivery after that sucks, you have to constantly follow up and query with a agent who never responds. When you try to contact her she is in a meeting but she can watsapp you. Now since vumatel has installed now I must laise with the service provider. After service is terrible be prepared to spend a lot of your time to follow up. I even stated to the consultant this service is terrible but no effort to turn around a customers situation. I work in a service industry and customer service is key, you should treat a client how you with want to be treated.
