Poor Customer Service.

I've been a short term vehicle insurance client of Momentum for about 3 years 6 months with no claims. Very recently I've replaced my vehicle and requested a short term car insurance quote for the new used vehicle and was quoted a monthly premium of R501.00. Since then a monthly premium of R746.27 per month have been debited from my bank account. I have then logged a compliant with reference COM****2004 and have made numerous calls to Momentum afterwards for an update as no-one could give me an answer other than the issue has been escalated. With my last call to Momentum I was informed that complaint case COM****2004 has been resolved. I'm now concerned that if this is the poor service I'm getting, will a legit claim be honored and what type of service will I get at that point in time. I'm definitely not going to call Momentum call center again regarding this matter as it's a waste of time. If a mistake was made, own up to it and take responsibility, just don't ignore your clients.
