After being sold car...

After being sold car insurance and being the 1st debit order in June.... The debit order went out... I did my car inspection and sent certificate for netstar.. I received a new policy with an increased amount.. But got debited an amount much higher.. When called the call center spoke to a consultant by the name of Gareth who didn't know what had happened and was to investigate and was to get back to me today but no response once again... The whatsapp service never works they don't even respond via whatsapp yet they have that communication available. Really disappointed after the sale there is no care being given to the customer so I can't imagine how much worse the claim process would be
