Terrible after sale service from Vodacom

Vodacom phoned me 2 months ago and offered me my upgrade over the phone. The salesperson suggested I get a Huawei handset , not telling me it is not Google supported. On realizing this, I immediately contacted Vodacom to return the phone. They said that RAM will collect it and then I can choose a different handset. This has been 5 weeks ago. Nothing has happened. I have phoned Vodacom 11 times and RAM twice. I get send from pillar to post and cant even get a reference number. Meanwhile I am paying for the new contract, but have no phone.

Worst service ever from Vodacom. I have been a client for 21 years, but are going to cancel my contract now.
