Terrible Customer service I have received from Vodacom Online.

I am very disappointed as I write this review, I purchased a Sumsung galaxy A12 phone CASH on my Vodacom app on the 6th on November 2021 and the phone was supposed to be delivered within 5 to 7 working days but up to now 2 weeks after I haven't received the delivery or phone call to update me what's happening ,I called Vodacom several times with no luck they are not helping at all right now they have blocked my number the only option I am left with is to email them but I have send several emails to *** with NO response ..I am very disappointed with Vodacom online customer service ...i went to a Vodacom shop they told me I must call customer service but right now they blocked my number I can't call ...I am very stressed.
