Disappointed and frustrated with vodacom.

I upgraded with vodacom 2 September 2020 and the sales consultant upgraded me with a I-phone 7 which included 175 airtime 1 gig per month and free cli all for 349 per month. I asked the consultant to repeat the deal which she did and she promised I would get my new handset within 5 days. Immediately after the call I got sms for 493 per month and ever since then I have phoned vodacom 3-4 times per day and I get no joy. I have asked for a supervisor or manager to contact me still no joy. Last Friday I phoned again and was told the I-phone 7 was discontinued. The consultant then told me they got the I-phone 8 and I said I wanted the same deal as it's not my fault. She was to get back to me. Today I phoned and can you believe vodacom blocked yes BLOCKED my number from calling the call centre 135. I get no joy from vodacom and their consultants is no help at all. They upgraded my contract but I have no handset. I currently have 3 contracts with vodacom and have been with them for almost 20 years.
