Vodacom service complain

I bought a 3 in 1 sim contract with router. The parcel was delivered on the 14 February 2023 and I waited for activation which was supposed to be within 24 hours. On 20 February 2023 I called Vodacom customer care and was taken from pillar to post. Now they blocked my number from contacting their line as the claim it had unusual high call volume. Even today the sim is not activated and I cannot get help from them. I went to Burgersfort tubatse crossing branch and I was told they cannot help me as this was an online purchase.
