Pathetic service from Vodacom

Ive been trying to upgrade my contracts for the past month with continously receiving pathethic service. Due to the unproffesional and pathetic service, i the customer has to take the brunt of their untrained staff. No effort in following up in any way to assist me to ensure a happy customer which I've been for over 20 years. One of the worst experiences i have had with any service provider in my life. Their unproffesional way of working with me through this has left me in a worst of position than i started. Afyer 20 years, I will never recommend this to anyone, rather choose a different service provider instead. Totally unhappy with the terrible service. Wish I could just give the phone back and cancel my account with them. Totally unproffesional right up to management. Pathetic service
