Rude Staff and really needing training in customer service!!

On the 30/11/22 I visited the La Lucia Mall branch of Vodacom. My experience was disappointing. The staff were cold, rude, unprofessional and ill mannered. The lady assisting actually told me to go onto Hello Peter and complain.... I actually raised my voice at her and not one person including a manager came to assist me. These staff need urgent training in customer service/ greeting and acknowledging people when they walk into the store.... Yes we all are busy but just acknowledge me..... Thank god I cancelled my contract after being a loyal client for 27 years.
